Many of you have probably heard of it, but Heroes of Newerth (http://www.heroesofnewerth.com) is essentially a stand-alone version of DoTA from the old WC3 custom maps. The game's a bit notorious for angry people, but if you can get past that and find a friendly group of people to play with, it's pretty enjoyable. In any case, there's a $10 promotion going on when you go through referral pages. Mine is http://heroesofnewerth.com/ref.php?r=W2C3WY5K (just be sure to uncheck the $20 coin package if you're cheap like me =P).
