The fighting combos are easier to come by, as they leave more room for error than arkham city. and a nice batcave lair. however the story is kind of lame, in that its tough to keep track of what you're doing even with the hints. A lot fewer collectibles and a nice tie into the arkham asylum game. Can't wat for Arkham Knight
I loved Arkham City, so by proxy, I also "love" Arkham Origins. It's essentially the same game, just different villains. Very little else is different.
That pretty much covers the positive. The biggest negatives I have with this game is that the controls are a little wonkier, and gliding sucks. Without using the fast travel option, getting around town isn't necessarily difficult per se, but it's definitely more difficult than it needs to be.
