What one XBOX 360 Achievement...
 

...are you most proud of achieving to-date, and why?

Personally, I would have to go with http://www.xbox360achievements.org/i...4/+rNBAQ==.jpg"Key To The City" in Grand Theft Auto IV. (100http://www.xbox360achievements.org/images/site/gp-g.jpg) Why? It represents the first time I ever got the 100% complete mark in any GTA game, period. The closest I had come was Grand Theft Auto: San Andreas, which I am far from 100% in. (Presently stuck at about 83-88%, can't be bothered to hunt down all the oysters and photo ops and whatnot...)

So, yeah, discuss, and have fun.

Dunno, have never really given a shit about achievements, cause I'm not that good at videogames outside of megaman.

Mile High Club. Key to the City is good too.

Press Start in The Simpsons game

Mine is the achievement of getting 1000 in saints row.
