If you've already played Rocksteady's amazing Arkham City, then Origins is going to feel like a clunky beta to its predecessor. It's not that the game isn't good, it's just that AC cast such a shadow that AO cant possibly compete. Play them in chronological order, (Origins, Asylum and City) and you will get far more out of this game.
Great game, but after a few levels my son was having issues with Batman floating up in the air, and the game would just stay like that. He restarted it a couple of times, with no success. I went online to see if there maybe were issues with this game, and sure enough! ...there was. Once you reach a certain level batman seems to fall up and floats above the city and that's pretty much it. You can't go on to the next level no matter what you try. Too bad...I would have given a better rating if it had worked!
