Gameproducer.net has an interesting competition going on right now. Juuso, the blog's founder, has said to game developers "convince me to buy your video game" and he will actually buy the games of developers that manage to convince him by the end of April. Then he'll say what games he bought (those are the winners I guess).
This is an interesting competition for gamers because there should be some interesting games listed there that you won't necessarily find on the big game portals. So why not head over there and see if anyone can convince *you* to buy their game!
