Not really. The actual combat was great, co-op was fun as hell, the levels were great, and the game had a great challenge on Hell but on Inferno the game was an unbalanced mess. However, on pc and Blizzard games, there are things called patches, and they patched the game just a few months after release, which fixed most, if not all, of these problems.
A game I dump 70 hours into in just a few weeks cannot possibly "suck" and D3 was still my top game last year next to WO3 despite its issues.
Just about the rest of Boresquad who played the fuck out of D3 when it came out agrees. Everyone except Lager, who seems to not have even beaten Nightmare
