First of all, I just want to say, some of you guys have issues. I don't see why I'm such a bad person because I gamesave. I didn't know that anyone had a problem with it (including Cheapy) until you all started bashing me. If you really want me off the leaderboard, Fine...but I'm taking the others down with me.
Lets start off, Nesmaster (the guy at #1) gamesaved Full Auto. His achievements are lined up unnaturally and it is obvious that he cheated on it (at least to me because I helped many people with the achieves in that game). He also SPGed Guitar Hero 2 to get the Expert/5*Expert achievements. Once again, he got the achievements illegitimately. So take him off the leaderboard.
The guys at number 2 (BigMes) did a lot of his games legit (like me), but I highly doubt he played through 30 years in Franchise Mode in Madden 06 and Madden 07. Although he doesn't use gamesaves, this guy plays games unfairly in order to get achievements. Did this guy really beat Guitar Hero 3 or hard/expert using a regular controller? I don't think so.
Edit: I'm back. Sorry to skip down to #13, but I was very curious to see if TomoyoN is really the legit gamer that you want on your leaderboard. He's not. First of all, he boosted his Prey achievements. Also, judging by his other Guitar Hero 2 achievements, I say there's no way in hell he could have beaten Jordan on expert legit (I did however, sorry to brag). Oh lordy, I guess hes not the angel you thought he was Cheapy. Look at his All Pro 2k8 achievements, he boosted for all the online achievements (hence the fact that he has all the online achieves before getting any other achievements, except Create A Team). Now things get really fishy, in Bulletwitch, this guy beat the game on Hell and Chaos on the same day. My knowledge of gamesaving tells me that is only possible through.....gamesaving! I would also like to direct your attention to his Bioshock achievements, which he SPGed! I dont want to look any further, the point is here. This guy is a cheater!
