Note on Spider-Man 2: I don't think PC (and possibly some others) should be listed among the platforms because the PC version (which I just recently happened to play) is so completely different game than the console versions.
This is somehow a year with very few games I've actually played. Though I fear that'll become more common, my expertise is 90's.
My candidates:
Sims 2: I did get much joy out of it, but despite that I still refuse to consider it a "game"
Tekken 5: best fighting game I've actually owned
Colin McRae Rally 2005 and Xpand Rally: two fine rally games
Star Wars: Battlefront: if I hadn't already voted Battlefield 1942, I might lean to this one
Myst IV: had the best story since original
I doubt it'll get a second vote, but I'll give it to Colin McRae Rally 2005, in some ways (of content and general structure) the best driving game I've played.
