Oh, don't get me wrong. I think it's a solid game. I played D1 & LOD for years, it was our LAN game.
D3 just has little replay value, and now has competition with WoW.
Old Diablo was incredible, but it also had no competition
Not at all criticizing, just predicting your return.
My friends all bought it.
They're all back to WoW. (A few are preparing for competitive Halo play admittedly)
