Ok before we start let's get this out of the way. I have no desire to start any flaming or arguments. I disagree with some of the new features and always online etc., but please don't post if that's all you have to contribute and you're not going to play anyway!
With that said, I'm still really excited for May 15th. I have the CE pre-ordered and am really looking forward to going through the artbook, documentary and soundtrack along with the game. Some might disagree but this is one CE that seems like it will be worth the high price.
I'm going to limit some of the features I'm going to allow myself to use so I don't spoil my D2 nostalgia and style of playing. No RMAH, no sharing of loot between characters (for the first few levels anyways) and one of every character besides three barbarians. I know I don't need to have three barbs because of the way skills work now, but I think I'll make one dual-wield, one shield and one two-hander just for fun. Otherwise witch doctor looks like a lot of fun, not entirely convinced by Demon Hunter yet but I didn't play much Amazon in D2 anyways.
There's a comprehensive comparison of the systems in D2 and D3 here:
It's written by a 'hardcore' player apparently and is well worth a read. I only played some nightmare mode of D2 and only played single player so I'm probably not in the 'hardcore' crowd even though I loved the game and played it a lot.
So, anyone else excited, know what characters they are gonna play etc.?
