Diablo 3 is the one I'll most likely play, Rift looks kind of like WoW tbh... But with a different story, different graphics and all that. But the style seems similar Lol. And I was never really a big fan of WoW. Or atleast.. I sucked at it xD
I was also thinking of playing DotA 2 and Guild Wars 2, but I kind of would prefer playing a game we all play
