No huge favorite for me this year, mostly 8/10 games: Paper Mario, Z:MM, BG2...
Some are special like Counter-Strike and Phantasy Star Online.
Several candidates of great reputation that I haven't played.
Honorary mentions to couple little personal favorites: Deep fighter (PC) and Robot Warlords (PS2).
I've never before pointed a game I'm definitely NOT voting, but in this case I have to mention Driver 2 was perhaps the most infuriating game I've ever played!
Leaves me three options: Dragon Quest VII, Icewind Dale and Sega GT.
Sega GT is very dear to me for nostalgia and aesthetics and general structure; but I have to admit some of driveability can be bad.
Icewind Dale is hugely underrated and overshadowed by BG, despite being IMO the better of the two. And specifically the first IWD is best of the games, expansions considered.
But I'll vote Dragon Quest VII.
