Cave Story was the game that introduced me to the world of independent gaming. It was hardly revolutionary, but that did not stop it from being an extremely fun and remarkable experience. Hard to believe it is a solo work.

Now *here* is a revolutionary game. Katamari Damacy is one of those few works that impede the mainstream industry from being exclusively made of reiterations of tried-and-proven genres. Also, it is great fun!

Portal was a triumph and a huge success. It is certainly the funniest and one of the best-written games I've ever played. I still laugh at most of GLaDOS's lines every time I replay it.

I have to confess Riven's gameplay was not what made it one of my favorite games - though the puzzles were great, what fascinates me the most in this game is the incredibly well-crafted world. Every single object has a purpose and reason to be that are not always explicit, and the environment tells a story on its own. Riven is also probably the most immersive game I've ever played.

Best multiplayer game ever. Very balanced and fun! The little details in the maps amaze me every time, and the gameplay changes a lot from class to class.
