I'm only gonna name one game from each series. If I didn't, it would be dominated by FF and GTA, probably.

1) Grand Theft Auto: San Andreas
2) Final Fantasy VII
3) Kingdom Hearts
4) GoldenEye
5) Command & Conquer: Red Alert
6) Pro Evolution Soccer 3 (When I get PES4 that will probably replace this)
7) Pokemon Red
8) Metal Gear Solid
9) Dynasty Warriors 4
10) Tekken 3

PS: Pokemon Snap is love.
