Seriously? You've never heard of Tim Schafer? Double Fine Productions, previously LucasArts? Tim is responsible for absolute classic games like Secret of Monkey Island, Day of the Tentacle, Grim Fandango, and of course, Psychonauts, Brütal Legend, and Stacking, from my list.
Super Meat Boy and Fez? They are very high profile indie games. Creators and games were also the subject of an excellent documentary: Indie Game: The Movie.
Wasteland. Created by Interplay Productions, and used as the basis for Fallout. You must have heard about the Fallout series of games, surely!
Bastion, To The Moon. More high profile indie games.
Actually, I didn't create my list with the idea that these games were famous. My criteria was more about quality. These are _excellent_ games. Very much recommended to play. It's just coincidence that some are well known. Anyone with a decent knowledge of gaming culture would know the all. I didn't even mention any of Valve's own games.
