Well, on PC I know it's a buggy mess that's not been fixed. In fact they went out and admitted that they didn't have intention of fixing any of the game breaking
glitches and bugs before they were done with all the DLC for the game. So yeah, **** that.
There are plenty of issues with the game on the PC, such as enemies randomly respawning when you turn your back on them (Literally the moment you do so) places you can't go, ledge you can't hang on to, falling through the floor, saves being corrupted, cutscenes grinding to a halt, and last but probably worst of all: A rare but devastating issue that may cause any
loading screen to force several thousands frames a second, effectively frying your GPU.
Apart from that I personally find the story to be somewhat bland and dull. The so-called 'twist' was no surprise at all, most of the bossfights are either unfair and utilizing inflated difficulty by throwing random adds in there (Yes, I'm looking at Bane in particular here.) or simply QTE events that drag on forever, with no real fighting involved. Actual Batman canon is completely disregarded, and there are several plotholes - How does Batman start the game
with technology that five years later would be less
effective, and apparently a dangerous prototype? Other than that there are the overly pretentious skill trees, and the combat system was actually downgraded somewhat.
Oh, and as a sidenote - I've played all the games Keyboard/Mouse, and found it to be far
easier and less complicated than either of my controllers.
