the actual story missions were shockingly short. but there is a TON of other stuff to do.How many hours is Arkham City? It seems huge in a good way.
It actually doesn't take that long to complete the campaign, but between the Joker puzzles and side missions and combat/stealth challenges, there's a huge amount of other stuff besides just the main story. Oh, and have fun with the AR training. A couple of those were almost controller-breaking.
