So, I made it to level 3 with my monk before the server crashed and my single player game was rendered useless until Actiblizzard gets their act together. Kinda lame.
All in all, I'm underwhelmed - shocking! Given, I'm level 3, but it still feels like the old one-dimensional click-fest that the other Diablo games have been. Torchlight is 1/3 the price and seems to scratch the same itch, so good on you Rudy for waiting for TL II - I think it would have been a better bet for me too.
All this being said, I'm LEVEL 3, so I have LOTS more to explore, but it gets a big MEH from me so far, and the fact that there is an always on Internet connection required for a single player game REALLY bugs me.
