Man, when you factor in Japanese release dates, 2000 was a spectacular year for N64: Perfect Dark, Majora's Mask, Banjo-Tooie, Sin & Punishment, Excitebike 64, WWF No Mercy, Paper Mario, etc.
Also, I wanted to highlight one 2000 game that has gone unmentioned: Dragon Blaze for arcades. Probably the best Psikyo shooter.
