What? No StarTropics? That should be in the top 5 at least...

With all the time in the world to play only video games... my picks would be 1 StarTropics (NES) 2 Oblivion (360) 3 Devil May Cry 3 (PS2) 4 Starcraft (PC) 5 Counter Strike (Xbox) These may not be my favorite games... but they would take up mucho time
