I have been interested in Steam for a while now, but my computer is old and falling apart, so I doubt it could run anything. But I did get a copy of Orange Box for PS3 for cheap. While I really enjoyed Half Life 2 and Portal, Team Fortress 2 is a real winner. It's brutal at times, but it's forgiving in other areas and doesn't take itself too seriously; the characters and dialogue are really funny. Unfortunately, the last few times I have tried to play it, PSN was full of ass and lag.
