I haven't played the order yet, but i'm sure if bloodborne will have any complains it won't be from being a single player, short experience with not good enough gameplay.
Maybe it won't sell as much as dark souls, thought i suspect it will move consoles as there's a very enthusiastic community around the souls franchise with no other way to play this game other than getting a ps4.
I, for one, have already taken some days off from work to focus on this game when it comes out next month.
