Ok gonna make an effort listing the rest here.
29: Broken Sword II: The Smoking Mirror (PC)
I originally had it on PS1 but the load time were annoying so bought a cheap PC copy with no load times. Point and click perfection this series, great story driven games, great challenging puzzles, great humour that keeps you playing even when stuck. Nicole isn't anywhere near as funny is George though and you needed play as her in this one.
28: Resident Evil 5 (PS3/360)
Screw the haters, this is the best co-op game made this gen. Every other co-op game with the exception of a few crappy ones just uses a single player game and throws in a co-op buddy. This thing is design around co-op and has the perfect pace to make it matter. Wesker was awesome in it and left behind more great quotes than the series combined.
27: Batman Arkham Asylum (PS3)
Nailed Batman, great bat-story, great bat-gameplay.
26: Combat (Atari 2600)
The tanks gameplay was what made this great, so simple yet fun, Tank Pong especially. The other modes/vehicles were mostly good too. If you owned an Atari 2600 you probably owned this.
