Kongregate is a website with some of the best flash games. My favorite flash game site by far. You earn badges, similar to xbox 360 achievements and level up. You can also buy kredz for special things in games. Another good thing it's for is forums. The most used is General gaming, serious discussion, and off topic. Although fun to be in the forums, OT/SD will be full of flamers, trolls, newfags, and oldfags. SD/OT also have a lot of obnoxious idiots who try to make themselves seem smarter then everybody. But, it still is fun.
