You know, the top guys really must spoil the whole achievement thing for themselves...as well as boosting, swapping hd saves and other ways of cheating, they play through games they can't possibly like and want to play, just to stay top.
I am proud of my achievements. I only recently reached 3,000 again on my console (I had to get a new one which sucked because i had just about 4,000 on the old one), but although I'm not the highest, or anywhere close, I know I only play games I like, and I worked for them.
They just seemed to have missed the point of it entirely.
