Kongregate

Kongregate is an just awesome gaming website that allows you do chat while playing games. Also, there are achievements such as badges and cards. If you get a badge, then you get some points depending on the difficulty of the achievement. Easy badges are worth 5, medium are worth 15, hard are worth 30, and impossible are worth 60. Each week on Friday night the creator of the website, Greg, will choose a game to become the Weekly Challenge. If you complete the weekly challenge you get a card for the TCG that will be coming soon.
