My time counter is at 14 hours, and I'm having fun. I'm only 14% through the story though, and supposedly the game takes about 7 hours to complete. So I must be exploring and fucking around a hell of a lot more than most people. Yeah, it's a bit different than Dead Rising 1 and 2, but I'm still having fun. I'm not a big fan of harsh time restrictions or escort quests, and I didn't feel like DR benefited from them.
Also, someone bought me a digital copy of this game for an early Christmas present. Problem is I bought it the night before, also digitally. So if anyone is thinking about picking this up digitally on Xbox, I have a digital copy I need to sell.
