Okay, so I haven't played NWN2 enough to really sing it's praises. One thing I can't wait to experience is the multiplayer side of it. Currently I am waiting for a specific server to stand up so I can play on a dedicated world. The URL escapes me now but I will post it later.
My Dungeons and Dragons group Gone4DnD (with the exception of my wife, she's too hooked with WoW) plans on creating a group of adventurers to play test the realm.
