1) Final Fantasy VII (Even if I start to prefer other games, the sheer impact it had at the time secures this at the top)
2) Final Fantasy series
3) GTA Series
4) Spider-Man 2: The Game (PS2)
5) The Zelda games on 64
6) Pro Evolution Soccer
7) Donkey Kong Country Series
8) Tony Hawk's Pro Skater Series
9) Super Smash Bros
10) Goldeneye

This is just off the top of my head, and not strictly current, but I think that's a fair list.
