I played this game's story mode 3 times (not including the bonus mode or the DLC's) and I'm still blown away by how incredible it is, I love the challenges and free-roaming Arkham City however if I had to pick something that was disappointing in the game I'd have to say it was kinda short. Lets face it, a real gamer will sit down and play for hours straight to beat the storymode, but once I beat the story there were only 3 or 4 mini missions to do after (some were even just teasers for the next game!). My advice is: Buy Arkham Asylum and play that before playing Arkham City, it'll show you just how incredible the game stepped up in just 3 years.
