Arkham Knight wasn't ass. It just had awful tank battles is all.
Yeah it's not like that awful part takes up 20% of the game. To the extent that you fight Deathstroke in a tank. It felt like you did more tank fighting than actual hand to hand fighting.
But yeah I guess they were the only bad part. Not the hilariously terrible story, extreme lack of boss battles, lame side content, and over focus on the batmobile.
Game was crap outside of it's graphics/production values and insane presentation.
