So I heard there are 4 acts and the entire game takes about 24 hours to complete, so correct me if i'm wrong but multiplayer is essentially co-op mode where you play through the same content again along with your friends. So all in all 48 hours of gameplay for 2 play throughs and 13 years of development. I can't understand how people are going to be playing multiplayer for years if its the same story and run-through everytime...I guess what i'm saying is why would people keep replaying the same thing over and over again to see the same quests and environments from before...maybe i'm missing something from multiplayer but why include a Auction House if most people 80% will play through the 4 acts and uninstall because a lot of people don't like co-op. So can somebody enlighten me?
