I've played around with DD, and now I'm going to invest the time into this cool game. What is the replay value? It's a big mark in my book (D2 is permanent on my HD as are some favorite roguelikes because of the replay value; Morrowind is the best replay game I've purchased for the Xbox). It seems like the plot and quests will be linear and the areas the same (not randomly generated). Replaying the game may require different styles, but if the quests are the same, et al., is it really worth it?
