I still think Arkham Knight is pretty weak compared to the other 2 rocksteady releases. I know that they probably thought the formula was getting a bit stale and added the Batmobile to spice things up, but to me the Batmobile was just not fun at all. The rest of the game was A+ tier but the batmobile legitimately occupied like a third of your playtime. Overall still a good game and I'd much rather replay it than play Gotham Knights from what I've seen.

Also, Arkham Knight's PC port was incredibly bad in an era where publishers were starting to take PC ports much more seriously. That really soured it's initial reputation despite being a good game under the bs. Dishonored 2 also suffered from this problem.
