31. Tactics Ogre
I have not played this game in 10 years or so. But what I remember was a great fun SRPG. that was deeper and better plot, than ff tactics. Quite unique! Though ofcourse I don't play many SRPG's so can't say for sure if they are unique. This is my favorite SRPG. I'm excited for the psp remake.
30. Half Life 2
At the time, it was extremely polished a bit linear. And extremeley immersive. Alyx Vance is one of my favorite characters in a game. Also this game has a bunch of other great characters and presents it in an immersive way. It also has an interesting story. Too bad Gordon Freeman is boring and doesn't talk (I don't like silent protagonist) and in my opinion brings the game down. And it had the gravity gun.
Also I would have included Episode 2 on the list becaues it's better than Half-Life 2 however I consider it not a whole game... And Half Life Episode 1 sucked pretty much imo.
Also I feel it's a bit too linear, kinda like another game coming up ;). But at the same time this game as excellent excellent pacing and this might have been sacrificed if not made this way. Which might be a bad thing.
I also realized I forgot perfect dark on my list haha.
