I have been lurking the new Beth forums off and on and I'm not really seeing much negativity anymore. Most of the people playing the game right now are simply enjoying it. Some claim to be bored, some want their money back, but the vast majority are playing it without complaint. In fact I went over to those forums specifically so I could find some good rant material to read as I was eating lunch yesterday (cheap entertainment, lol). At worst, gamers are complaining about minor facets of the game, mostly balancing issues between players / loot / monsters, etc.
I'm not playing it, I have no interest in MMOs or co-ops, but I do like keeping tabs on what's going on.
