Have they said how much gameplay the Harley Quinn pre-order thing is? GameFly just shipped the PS4 version to me, so I won't be getting that, and I'm curious if it's a minor pre-order bonus or if it's a basically the equivalent of an 'online pass' like Catwoman was in Arkham City. Googling it gives articles that are conflicted about whether it's just challenge maps or part of the main game.
Edit: Also, Asylum >>>> City, and Origins was so bad I couldn't even make myself finish it. Bugs were a big part of that, yes, but mostly it was how badly the C-team screwed up the combat.
