I think mabey you could get achivements for different things, like: 5,000 posts, 250 games rated, get 10,000 Ap, have over 25 merits, and much more! And each time you get an achivement, you could unlock a new set of exclusive armatars only availible through unlocking achivements!
@ Drognar Many games have given you awards for achievements. Like X-box live gamer points and Team Fortress two lets you unlock new weapons.
There should be a small button next to every game icon that adds it to your "to play" list on your profile. Cuz I can't play every game I want and lots of them look interesting. That way when I come on I can see what games I haven't played but want to. At least something like that...
