Recently released games aren't as great and innovative as they should be; I highly doubt that Call of Duty: Modern Warfare 2, however great it may be, is going to still be talked about 10 years from now.
Legend of Zelda OoT Super smash bros (the original) KotOR 1 Bioshock James Bond Goldeneye Orange Box (even though it contains more then one game) Fallout series Diablo 2 Starcraft Prince of Persia SoT Baldurs Gate 1 and 2
Those are my favourite games of all time. And Yoda Stories. I loved it. If I had to choose one I think I would choose KotOr, but it's extremely close.
