I've commented about the game in another thread. I think the game is awesome and I love going through it with the different costume options, especially the Adam West, Michael Keaton, Christian Bale and Ben Affleck suits with their respective Batmobiles.
The only negatives I have towards the game is too many tank battles, not being able to use any of the other characters in story/freemode, villain battles were lackluster compared to past games and the Arkham Knight reveal was completely disappointing because I figured out who the Arkham Knight was long before the game launched.
Also you should go to the settings menu and change the Batmobile controls so that L2/Left trigger is your reverse control. I had a lot more fun with the Batmobile after doing that.
