So i got my 360 in early to mid March, i don't remember the exact date. I never even knew what an achievement was and didn't care if i even had any so i just played games and whatever unlocked through normal playing is what i had. The only game that i actively tried to get cheese for was UFC and that was still just normal playing with a couple exceptions. Then somewhere along the way when i was getting into the thousands of points i thought maybe i should go ahead and try for some and maybe finish a couple games. I have gotten somewhere around 5000 achievement points in a little over 2 weeks, i have 3 1000s so far (a couple others finished as far as i'm concerned due to online achievements i doubt i'll do) and am now sitting at 10,130. It's pretty cool seeing 5 digits there.
