Single Player: Robotron 2084 (Arcade - NOT Xbox Live), 29 years and I still enjoy it.
Multi-player: Left 4 Dead 2 (Xbox 360), 3 years and counting.
(Doom 2 and Rock Band are close seconds. Also, surprised at how few Minecraft answers considering how loved it was a few short months ago. I see it's not completely unloved but the way people were talking about it I thought there would be more).
