Doom might arguably be the most memorable (or at least the most popular) PC game of all time, and with good reason. Prior to Doom's release, programmers found themselves in the stone age of game development. For the most part, building a game meant starting from scratch and compiling all new code, but like the invention of the wheel, the advent of the game engine forever changed the PC gaming landscape.
Now, we know what you're thinking, and we're well aware that game engines existed prior to Doom's release in 1993; we're even going to cover some. But it was id Software's now legendary first-person shooter that pushed reusable 3D game engines as a viable programming model, and videogame development has never been the same since then.
On the following pages, we look back at all the major PC game engines and what made each one special. As a prerequisite, be sure to check out our history of 3D graphics, which covers videocards from the Voodoo to the GeForce and everything in between. Once you've digested these two features, you're guaranteed to have a new-found respect for gaming on the PC!
What would eventually morph into the Ultima Underworld engine started off several years prior as the Space Rogue engine, named after the sci-fi game with the same name released in 1989. Naming a game's engine after the game itself is a practice that, to some extent, lives on today.
After releasing Space Rogue, Origin Systems began work on Ultima Underworld and its accompanying engine. After a bit of work, an algorithm was developed that allowed for texture mapping, which was applied to walls, floors, and ceilings. The development team would add varying height throughout the map for a 3D effect, as well as inclined surfaces.
NPCs consisted of two-dimensional sprites, but objects were rendered in 3D. This, along with the use of physics to create movement, bogged the engine down. This led to Ultima Underworld running slow even on higher-end 486DX systems at the time, though system requirements called for a 386-based PC.
Date Released: 1990
Notable Games: Space Rogue, Ultima Underworld:The Stygian Abyss
Id Software's Doom engine wasn't actually a true 3D engine at all, but a very well conceived two dimensional sector-based engine with 2D sprites representing objects, characters, and anything not tied down to the map. Because of this 2D limitation, rooms could not be stacked on top of one another, but this also allowed for faster rendering on the less powerful hardware of the time. All that was needed to run Doom was a 386 level PC (in low-detail mode) with a standard VGA videocard capable of rendering texture-mapped environments.
Despite the underlying 2D nature, Doom was, and still is, considered a 3D title. Id created the illusion of 3D with height differences added separately to the environment, and later titles built around the Doom engine would even implement the ability to look up and down, albeit with a distorted view.
Date Released: 1993
Notable Games: Chex Quest 1+2, Doom, Doom II, HacX, Heretic, HeXen, Strife
Every Comanche game ever made was constructed with some form of NovaLogic's proprietary Voxel Space engine, while several other games implemented voxels for specific parts, like rendering vehicles or in-game items.
A combination of the worlds volumetric and pixel, a voxel is a way to represent volumetric objects as three dimensional bitmaps rather than vectors. Think of a stack of legos with each piece representing a voxel, and you get an idea of how the Voxel Space engine rendered terrain. Only these were really 2D bricks with varying height. By rendering terrain this way, graphics were more smoothly contoured and detailed than other flight simulations using vector graphics, along with offering smoother gameplay.
Date Released: 1992
Notable Games: Blade Runner (characters and artifacts), Comanche series, Command & Conquer: Tiberian Sun and Command & Conquer: Red Alert 2 (most vehicles), Delta Force series, Master of Orion III (space battles and solar systems)

Okay, I know it started on the Mac, but Marathon was out before, if not at the same time as Doom and was the first to feature mouselook. (well there was "Pathways Into Darkness" before that). However the point is that Marathon 2 was a very well liked engine for PC (and the series is of course the unofficial predecessor of the Halo series.) And it was doing Doom better than Doom did. It was also a better story. Additionally, the multiplayer boards were always acclaimed as being some of the most enjoyable.
That said, I can see why it wasn't mentioned, as it really wasn't used in an excessive amount of other games.
Anyone interested, it's a series that still holds up today. Go and find it.

What about Wolfenstein 3D's engine, which predates doom, and was used for many classic games.
Wolfenstein 3D, Spear Of Destiny, Blake Stone, Planet Strike, Rise of the Triad...
How can you leave out this revolutionary engine, and skip directly to Doom's engine???
You also totally skipped over the Tomb Raider engine incarnations from CORE! come on guys!

RE: (concerning Quake3): "The newer engine marked a departure from skeletal animation and instead
made use of per-vertex animation. Without diving into the technical
details of both, the switch paved the way for smoother animation."The Quake 1 and 2 engines (which were very similar) did not use skeletal animation. Both used per-vertex animation, like Quake 3.
The reason Quake 3's animations were of higher quality is because the vertex coordinates weren't compressed (quantized) so aggressively. Quake 1 and 2 stored vertex coordinates with 8 bits per component (each of X, Y, Z), while Quake 3 used 16 bits per component. Quake 1 and 2's aggressive compression led to an ugly effect known as "vertex swimming".
Also, Quake 3's animations were created with more keyframes, generally 20 to 30 per second, whereas all animations in Quake and Quake 2 were created at 10 frames per second. But that's not nearly as noticeable as the compression.

Great article on the history of game engines but HOW COULD YOU LEAVE OUT BULLFROG??? Anyone remember the Magic Carpet Engine? What about the greatest PC shoot'em up - racing game of all time, Hioctane??? You owe us a seperate article devoted to Bullfrog, with a focus on Hioctane's amazing if not quirky AI.

AFAIK, there's not a single line of code from space rogue's engine in ultima underworld's.
The underworld engine was the engine from the (best left forgotten) Car+Driver game, augmented with an upper layer to handle interior environments modelled on a grid. The texture mapper that drew the billboards in c+d is basically the same one that drew the walls in UU.

So they acknowledge Renderware as a key engine in the last generation but neglect to mention that it was used in one of the biggest titles in that generation, namely the GTA III trilogy (GTA 3, Vice City, Sandreas). That's a massive oversight, no? That would be like talking about the Unreal engine in today's market and not mentioning Gears of War or something. Seems like some one didn't do much research or has limited games knowledge.

It would be a lot more of work, but it would become a "wikipedia article" if each game would have a video with FPS ON THE SAME MODERN MACHINE, and benchmark tests.
And of course a picture of each game, links to where to buy, or where to download - some are now free or abandonware - or even where to play online, there are versions of doom and hexen online.
I missed GLdoom that ported wads to a opengl engine.

I gotta agree with John P.: yeah, I know Diablo 2 is old, not true 3D, and uses sprites on a background; but it, and other Blizzard games are Popular. The D2 ladders are still full! The news of Diablo Three has caused firestorms! I still love the bird's eye camera, no-fuss controls, and gameplay as simple or complicated as you want (normal, NM, or hell difficulty). I have a bunch of character classes at different points along the game.
The only reason I don't play online is because of all the PlayerKillers and Cheaters Duping and selling items-for real cash. But that's gotta tell ya something about popular! I'll get set in a comfy chair, mouse table, hand-held keypad, and just lose myself for a while. Like a peaceful walk by a mountain stream, with a$$kicking. And I'm preordering D3 as soon as I save the money. (I've got some other upgrades going on.)

I'd really like to know a little more about the Halo and WoW engines as well, more so Halo, but I doubt they are used for any other games.

I wonder what kind of engine runs World of Warcraft? No loading levels, low system requirements, tons of toons and NPC's on the screen at once, AND it is the more often played game in the world.
and how about Starcraft or even Starcraft 2? What are they using?
Blizzard should have definitely been mentioned in this article! Well perhaps not, as whatever engine they used, it was only used for their own games.
Anyone know?

That is one thing that Blizzard has never really talked about is their game engines. I guess since they do not share it with anyone else, it's a "don't care" attitude. What you see is what you get...

S.T.A.L.K.E.R.'s game engine might have been overshadowed by the Crysis engine, but it is still pretty impressive, especially with all the DirectX 10 effects like the dynamic wet surfaces and such. How could you leave that one out?

Setting the record straight: Space Rogue was not developed by Origin. It was a contract game written by Paul Neurath and published by Origin. Nor did Origin develop Underworld (or System Shock, or Underworld 2). They were produced by Origin, but all of those games were developed by Blue Sky (later the legendary Looking Glass Studios).

Excellent article!
Long ago, I played the demo for an FPS. Years later all I could remember of the game was that the player collected money that could be used to purchase items from a merchant in a town, and that there was some sort of electric weapon the player acquired early on in the game. I could never find that game again, but thanks to this article I know that game was called Strife! Thanks MaxPC!
Time for some retro gaming...

Dungeon Master from FTL Games was the first game engine that worked as "a viable programming model." It was released in 1987. The same code base for Dungeon Master (DM) would build on the Amiga, Apple IIGS, Atari ST, PC, SNES, TurboGrafx-CD, Sharp X68000, PC-9801 and FM Towns. The same game engine was used to produce four more titles.
DM set the standard for adventure games in terms of the user interface and playability. The Ultima Underworld GUI looks remarkably like DM. DM was also the first 3D looking, first person, real-time adventure game.
As a plus, DM was also the #1 selling game on the Amiga, Apple IIGS, Atari ST and PC all at the same time. Doom the first? Pffft! Give me a break!

Far Cry 2's Technical Director, pointed out in an interview with Gamasutra that they had Far Cry 2 running on a Pentium 4-class processor with a GeForce 6600 graphics card.
Its true! I played Far cry on medium settings using pentium 4 3ghz and 8400gs (which is close to 6600)
Still nothing beats source engine! And what engine does COD 4 uses? It seems efficient too

once wolfenstein is released would you kindly add id Tech 5 engine
also include Cry Engine 2 for Crysis 2.
bjtalbot
July 21, 2009 at 1:06pm
If you look up "id tech 4" in wikipedia, you will find that the new Wolfentein is using id tech 4.
As far as I know, the only games that have been announced to use id tech 5 are Rage and Doom 4.

The worst engine on this list is the unreal 3 engine by a mile; I bought UT3
a while back and played it for less than ten hours total. The sound went out in
the game for some reason, never could find a solution and gave up on it. It's
horrible on the eyes, the world melts together with the characters and objects
and all looks the same. I realized after Bioshock that the non-world objects
are extremely choppy in their animation. And I hate how most DX10 games either
look no better with AA or don't support it at all, it's like they think we
don't want it anymore.My favorites are the Quake III, Unreal I & II, and Source Engines. They
all contain games that are found on many top 5 games list

Uh, Descent? I'm surprised Descent wasn't mentioned at all. It had graphics almost on par with quake, and the demo was released in '94.
If I recall, that segmented software renderer Volition created (which removed the need for BSP trees), was used in one other game.
You can have your recession. I'm not participating.

I was pretty taken aback by the fact that this list of influential 3D engines fails to mention ANY of the Descent titles. Parallax/Interplay's Portal Engine used in Descent II was far and away the best of the bunch when it debuted in 1996. Unlike all of the other FPS games out at the time, Descent II allowed the player to take advantage of 6 degrees of freedom in moving about the gameworld space. This gave rise to the concept of tri-chording, whereby the player would apply forward thrust (Z) while also sliding (strafing) on both the horizontal (x) and vertical axis (Y). The combination of these movements, once mastered, actually allowed the ship to fly faster than it could simply applying forward thrust.
All in all it was a ridiculously well made, entertaining game that still holds a small cult following today...
Descent III raised the stakes, adding portal rendering, procedural texturing, and advanced lighting. When it was released in mid 1999, it was probably the most graphically advanced game of its time.

I think the Best Engine ever was Unreal because nothing could touch it when it came out and 2 generations later the Unreal3 Engine still looks beautiful and plays smooth. Next to that Voxel would be my fav oldschool, because C&C looked damn good, and Source as best new because its an evolving engine that next to CryEngine sets bench marks for others, and Source has pushed out so many great games in its still going life. My only big question would be if HL2 Ep3 will run off Source, a newer version as Ep2 did, or stay the same or will Valve deliver Source2 or something to show us how badass HL3 will look like on its relase date (whenever the game is set to come out.)

Call of Duty was made using the Quake 3 Team Arena engine, I'm sure of it. Then CoD2 and 4 where made use an extremely heavily modified version of the Q3TA engine, even the cvar's are the same as quake. I think because it was so heavily modified that they just said fuck it, we're calling it proprietary.
Also, why in pretty much all UE3 games is console BOUND TO FUCKING '. It's the most retarded fucking binding ever, yet it exists in all UE3 games.

norman
July 20, 2009 at 9:54pm
I believe the engine that powers Ghostbusters is proprietary -- that is it's not a licensed engine like Unreal Engine 3. However, it hasn't been out for a while to make any waves in the development community. There are many more proprietary game engines that we didn't mention which appeared in only one or two games. We chose to focus on the ones that have pushed technology forward and excited us as gamers and hardware enthusiasts.
