Eh, it was okay. The story was good, better than AC in my opinion, but the game overall was just... Disappointing. The Batmobile is way overused, with nearly every single boss fight being something to do with the Batmobile.
When I heard Deathstroke on the comms, I was really excited for another Arkham Origins-type battle against him. Nope, tank battle. Disappointing. Let's hope the upcoming DLC with a bunch of new villains gives us some real boss fights. Also the reveal of the Arkham Knight was really easy to predict. It took me around 3 hours to correctly guess who he was, especially with all the talk of Red Hood and having read Under the Red Hood before.
I had pre-ordered the limited edition for PC (big mistake) because I love the games, and didn't hear about the issues on PC until the CD key had already been used. Hey WB, where's our compensation for this awful port thing you gave us?
But really, while disappointing to a fan, it is still a really good game. Just those few minor complaints about the over-use of the tank battles. I would recommend it!
