The Game Boy: Games That Matter More Than the Games of the Year
Minecraft

Yes, I know Minecraft's technically been available since 2009, but it led the charge on so many of 2011's biggest steps forward that I had to include it. (Also, it didn't officially leave beta until last month, so take that, calendars.)
Foremost, Minecraft gave the indie movement a recognizable face, helping it grow to the point where, say, Terraria could go toe-to-combat-boot with Modern Warfare 3 for a top spot on Steam. Further, it validated an open development model by involving players every step of the way. With games now growing increasingly reliant upon post-release patches and DLC, Minecraft's mindset is the next logical step. Is it right for all games? Of course not. But it's a very appetizing proposition, especially given the newfound popularity of things like Kickstarter funding.
Overall, this has been an absolutely incredible year for indie games, and Minecraft deserves a big, pixelated pat on the back for lending a hand.
From Dust

From Dust was a great idea wrapped in a mediocre game. But that's not why it's here. Somewhat incredibly, it managed to be nearly everything that's currently wrong with PC gaming all at once. It kicked off its freefall dive into a canyon populated exclusively by cacti and woodchippers with one of Ubisoft's trademark month-long delays. Why? No real reason was given -- but obviously, it was an attempted middle finger to pirates. Unfortunately, waving said finger in pirates' faces only made them angry, causing them to bite back with more piracy.
Next up, dishonesty. Ubisoft initially promised that From Dust would kick the publisher's reviled “always on” DRM to the curb. Then it didn't, and Ubisoft tried to hide its red hands by deleting all evidence of its previous promise. Eventually, however, it was forced to patch out the draconian menace due to overwhelming outrage.
Even then, though, From Dust's PC port was horrendous. Among other things, it was locked at 30 FPS, lacked anti-aliasing, and was generally unstable. Ultimately, Steam was forced to offer refunds. Other developers, of course, employ each of those practices separately, but From Dust made the freaking planets align. Which is just another strike against it, honestly. Maybe I liked my planets all disorganized and un-apocalypse-causing.
League of Legends

Yes, yes, LoL's been around since the days when it was still clever to turn Internet acronyms for laughter into videogame names. And no, I don't have a Minecraft-style loophole for this one. You caught me. In penance, I'll put my lie-spewing hands in a waffle iron. I won't turn it on, of course. Why, that'd be silly.
Anyway, 2011's almost certain to go down in history as the year free-to-play went from foreign novelty to ultra-successful business model, and few games have benefitted more than LoL. Further, unlike potential flashes in the pan like DC Universe and every other MMO ever, LoL's a bonafide long-term success story. The game's been free-to-play since day one, and it hasn't stumbled since.
LoL's also a big name in the eSports scene, which has grown tremendously in the past year. Along with national-sport-sized hits like StarCraft II, Riot's massive MOBA has helped propel pro gaming to new heights, offering multi-million dollar prize pools each season.
Bulletstorm/Saints Row 3

Two words: dumb fun. Both of these games blasted and, er, dildo-smashed their way through all the slow-building, yawn-inducing epics and “srs bsns” multiplayer modes to remind us that, yes, games can be over-the-top, gleefully profane, and -- most importantly -- fun. Screw saving the world. I just want to remote-control a robot dinosaur with laser vision and go surfing on fighter jets.
