Finally putting time into this game. Performance on my GTX 970 is still iffy, but mostly good. I can get 60fps during the bulk of the gameplay, but there are some nasty drops while driving, and under certain conditions. The first gunrunner mission dropped to 20fps and stayed there. The game does look fantastic, though.
I'm 70% done with the main mission, and my thoughts so far are...
+Graphics
+Conroy and Hamill, sweeeeet!
+Gliding around feels amazing.
+Combat is mostly the same or better.
+The open world design is much better than the bland sandbox of the previous two games.
+Lip syncing isn't horrible this time.
+I like Batman, and in this game I am Batman.
-The XCOM habit of having NPCs never shut the fuck up trying to get your attention, and all the whining audio you have to listen to.
-The Batmobile was fun for 30 minutes, now I wish it wasn't in the game.
-A weird balance of some interesting dark storytelling, but with a bunch of cheesy comic book dialog that now feels more out of place IMO.
-Side content seems to be there to pad and now annoy, rather than just being some extra content for people that enjoy that thing. Rocksteady is famous for their collectables, but wow. The city is great, but now it's filled with all sorts of repetitive shit like drones and tanks. I remember reading that the "true" ending is locked behind 100% game completion, so if true, that sucks pretty bad.
Damn are there a lot of tank missions near the very end of the story. That's going to kill any chance of me replaying the game.
