I nominate gametz, they have a pretty good system there. But CAG is better for everything else like deals, contest, lowballs, etc. & especially community.
Despite not having much of 2012 to work with, the number of quality trades I was able to conduct in that small amount of time was astonishing; giving Goozex a real run for its money, a site that had the whole year to impress (and subsequently disappoint) me.
1. Games move both ways.
2. Super friendly community
3. Amazing CEO that responds to questions quickly and is a gamer not a suit
4. Awesome competitions
Is this category really necessary when you're including CAG? It's like going into Burger King and being asked if you prefer the Whopper or Big Mac. Even feels like those contests where the fine print says "employees and their families aren't eligible." Pretty lame.
