I am really hoping this game is actually better than Diablo 2. With the Lord of Destruction expansion and all I kind of doubt it, but maybe Blizzard will surprise me.
I've played through D2 and LoD and I have to say that D3 totally meets most of my expectations. The ambience and atmosphere in game are much much better than in D1 or D2, and graphic wise, night and day. I can't wait for retail.
Now if only the beta would work for me. I plan to beat the beta once with each class to see what I will be playing in retail.
