My brother recently got Diablo 3, and thinks it is great fun (even though he isn't fond of the streamlined and dumbed down aspects). Between installing the game, creating a battlenet account and downloading a very large required update, it took him 3 days to get to play, and then the router he was using died (just the internet access for the single player mode was enough for me to give it a pass). A week ago his monk was level 9, and he had yet to use a potion.
