- Counter-Strike Source - 1.6 is very good, but Source version is a fuckin mistake. Maps sucks, recoil nearly equal to 0 and fucked hitboxes... I bought this game just to have maps and models for playing Garry's Mod online ;p
- Half-Life 2: Deathmatch - to kill someone you need to shoot whole SMGs cartridge o_o . And always some noobs are destroying gravity gun fun games

. How good, that it's free for Nvidia and ATI users...
- World of Warcraft - I really hate graphic in it
- Worms 3D and later 3D versions of Worms - shame for classical series. Still nothing can beat Worms World Party ;D
- GTA San Andreas - 1,2 and Vice City were fun, but that later one sucks. Too realistic. Like for me, it's more Sims than GTA.
- Codename Gordon - 2D platform game with worse graphic design than Jazz Jackrabbit 2 (which was really cool, and has nice graphics), and it slows on 1,8GHz CPU o_o ...
- SPORE - very good idea, but game is boring... And these candy graphics are really shitty. Only one good thing was monster creator, but doing penis monsters after few days was boring too.
That's not all games which I don't like, but at this time I remembered only these ones ;p
