1. Super Mario Land 2: 6 Golden Coins
The first game (other than tetris) I ever played on my Gameboy. Startling, I've played this more than any other mario game ever made.
2. Grim Fandango
I just locked an open door... strange, yet symbolically compelling.
3. Final Fantasy XII
Finally killing Bullcroc was the greatest achievement of my life, at the time.
4. Mass Effect 2
Played as a female renegade soldier named Cunny. Nuff said.
