Anyone playing it?
I've only played the tutorial (which was super boring) and an hour or so of the main story (which was much much better). It's closer to GTA than it is to Fallout or Skyrim, IMO. By that I mean it's less free-form because your character has a pre-defined personality/motivation/whatever, and a little arcade in that you can flying-double-dropkick zombies in the face.
Still pretty enjoyable. Got fucked up pretty hard by the crazy night zombies, though.
