Guess that makes me susceptible of being called a mainstream/Nolan batman fan, except I'm not really even a batman fan, I just happen to like some of the films that have the batman in them.
I logged some 20 hours of AA and still haven't finished it (you know me) because I played it as a 3D Mark of the Ninja / FEZ / Trine hybrid (the Trine, sorry, Scarecrow parts felt the weakest to me), my iterative/completionist approach doesn't work well with it since you can't get all the collectibles unless you've already unlocked all the toys, at the same time I didn't loathe backtracking as much as I did with, say, The Witcher, because the levels are so beautiful and atmospheric that exploring them is a pleasure (that is also very Trine-y) and also it felt like a treasure hunt, the macguffin itself is not the point (and of course you can't make me care one bit about the backstory of some inanely uninteresting sidekick of a totally ridiculous supervillain, or some slow speaking Arkham guy, it's just noise in the background), the hunt itself is the point (FEZ understands this perfectly)
As for the dance/fight mechanic, well it looks good on-screen but even the much simpler execution mechanic of MotN felt more pleasurable, which prompts the thought that AA is a collection of systems that could be games on their own, but since they aren't, they aren't well developed enough to be interesting, ending up to be ...filler. Competently delivered filler, but still failing to hit the spot, gelling together just enough and mainly because of the package that holds them in place.
I should probably finish the main story (cross one off the backlog and all that), but that leads my mind to AC. There's probably more of that good stuff that I liked, and a whole lot more of that uninteresting fluff. Well, at least now, I'd walk in with more awareness and maybe be able to get more (and more eclectical) enjoyment out of it.
