Same deal as Left 4 Dead imo; great time with friends, but when you fly solo, you realise the game's kinda meh. Both are built around the idea of having friends, so maybe it's unfair to critique that element, but at that point, is it really the game you're enjoying, or the company you have with you?

Either way, the heist mechanics here are still better than GTA V's, so this was something to migrate to when we got tired of that game.
