I found this place when I heard someone mention on GAF about a place where demi, Drinky, MAF, and other GAF "retirees" hang out, did a bit of detective work and ended up here.
Pretty much echoing what others have said:
-Many of GAF's best and former best posters are here
-I prefer the smaller discussion, you don't feel lost in the crowd
-People here usually actually discuss and pick apart games, and rarely dive into sales-age melodrama
-Tends to be a bit more lighthearted and less melodramatic, I've gotten into arguments with people on here from time to time but it's not as bad as GAF
-More open, more free... easier to speak your mind, occasionally make stupid racist/misogynistic jokes without the threat of banz0rz.
