Knew I'd remember some other games that deserved inclusion on my list once I thought about it a little more. Hopefully this'll be it after these few latecomers:
Super Mario Bros. 3 (1990)
How did I forget this? I got Mario 64, but I think it's probably blasphemy to leave this one out.
Halo (2001)
I still like the original
Halo the best. It had the best sound design of its generation (just one part of a superb overall cinematic-feeling presentation), along with the most compelling campaign among any of the
Halo games.
Capcom vs. SNK 2 (2001)
Everyone knows
Street Fighter... fewer in the States know SNK, but they're big in Japan, with games such as
King of Fighters,
Samurai Shodown, and
Fatal Fury. This game features a huge cast of characters from both developers, and allows up to three characters on a team. There's even a "groove" system that allows different players to have different types of game mechanics -- like air blocking, just defense, rolling, dodging, short jumps, different types of super meters. All of it made for a hugely customizable 2D fighting experience that remains one of the best ever to this day.
Grand Theft Auto: San Andreas (2004)
Here's another one I can't believe I forgot. Grand Theft Auto should be represented somewhere in my list, and San Andreas just seemed like the best version, although all of them are good... it's sort of up for grabs.
