It's hard to pick just one... Street Fighter 2 (while it's not the best in the series... it's the one that had the biggest impact on me) Ninja Gaiden (on the NES) Contra (on the NES) Phantasy Star Online (countless hours spent playing that game) Chrono Trigger Castlevania SOTN
My favorite current game is Saint's Row The Third followed closely by Borderlands 2. It's everything GTA4 should have been. I'm hoping they don't fail me with GTA 5.
