but for now I wanted to bring up some interesting bits about the console version of the game, including the following: You’ll be able to play offline, with up to four players on the same console.“It’s so much fun,” Joshua Mosqueira, the game's lead designer, said when I asked how the couch co-op played. “On a big couch, with four of your friends, drinking beers, it’s almost like a party atmosphere. There’s this really awesome social moment with a legendary drop, and everyone is cheering. It feels very collaborative.”
There was some question about the offline play of the game, something that’s impossible in the PC version of Diablo 3. It was confirmed to me that the game will be playable offline on the PlayStation 3.TL;DR: Blizzard shits all over PC gamers, again.Even though some things were lost, and there will be many Diablo players who consider those losses a good thing, the gains were worth it. “But we really felt that playing offline, and being able to move your console from the living room to your bedroom, which a lot of players do to play, is really important,” Mosqueira said.
( Yes, I know I posted speculation about this in the past, but this is a real confirmation of it. )
