Am I thrilled they had these problems? No wasn't very happy about it but I also know from the open beta experience that within a day it is 95% fixed and by day two you didn't even know there was a problem. I can suffer for two days and yeah I am a blizzard fanboi, I don't deny it, I said it before. I think they make fantastic games, games so good that I am willing to give them a pass on the launch day issues. Now a month down the road and there are still issues then yeah I'll be pissed.
Also practically EVERY MMO has launch day issues and though Diablo III is not an MMO due the logon it is an MMO so the launch day issues apply.
Hell the much hailed (deservedly so) SWTOR had launch day issues.
You want me to ***** about issues, the NHL series has so many fucking bugs in it, the Madden series hasn't being a technical masterpiece for quite some time.
So back to Diablo III take away the logon issues, can someone tell me any game mechanics issues? Yeah there is one, a Demon Hunter cannot give a templar a shield because it causes a server disconnect. That's the only repeated issue I've heard about, from my experience the mechanics all work, the gameplay is solid, sound is sound, graphics are bit dated.
