I'm well into this now.
Like others, it took me a while. After playing Asylum and City the new controls pissed me off to no end, but once you've sunk a few hours in you get used to it. I still press the wrong button every now and again though. (Detective mode mainly).
Batmobile.. I've gotten used to it a bit now. Doing the chases and some of the riddler missions has given me a better grasp on the handling. Drifting is pretty easy now and helps loads.
So yeah, thoroughly enjoying it now after a slow start. Just getting data from the batwing (main story) so don't know how long to go. Completed a fair few side missions and a few are still locked.
Very well done game and excellently voice acted, as usual.
