One of the big themes to this year's QuakeCon is the idea that id Software wants to put a new emphasis on making games that are fun. The creaters of Quake and Doom are well-known for the technical prowess and graphical achivement in their games, but it sounds like they realized that a few of their most recent games were missing a key ingredient: Fun.
At this year's keynote, John Carmack used the "F" word (fun, of course) when describing id Software's upcoming projects: Quake Live, Rage, and Doom 2 RPG. For Quake Live, they are tweaking the matchmaking to ensure that players of all skill levels can have fun. With Rage, the only word they'll give about a release date is that it'll ship "when it's fun and when it's done."
