Great scores, so I'll jump.
I never finished Arkham City, allthough I liked it. It was one of those games the open world in my opinion worked against it. Asylum is one of my favourite games ever because it presents such a great adventure in a tight but believable location. It has awesome pacing, but lots to do on the side as well. In City I just, I don't know. Got sidetracked all the time, and lost the motivation to funnel trough the story because of it. It was the main reason I skipped Origins.
So I'm a bit wary about this one. I would give everything for a Asylum-esque tight adventure. But I can't skip on a seeminly awesome sequel on one of my fav games...
