Arkham City is the best Batman game ever. I have already played out dozens of times, the fun factor is always very high. Rocksteady has made the latest immortal with Arkham City. The GOTY Edition by Harley Quinn's Revenge is unnötigt my opinion. At the main story is not the point, it does not work so well thought out as AC. The big selling point is that you can play as Robin. That was also the reason why I had brought it to me then. Not Batman freaks can do without it.
