Realm of the Mad God, eh?
It's a good game with amazing multiplayer features, but I don't really think many people can get hooked on to it as you lose everything once you die.

Although, considering the fact that you can buy weapons and such, I believe that they killed the marketing system. Marketing was most likely my favorite part of the game. D;
