Batman Arkham City

The enormous city in Arkham City is incredible, from as low as the underground sewers to as the tip of every rooftop, everywhere is wide open to explore, and highly detailed, with extra bonus items to look for once the story is completed. Its all the detail scattered in the city that makes it all the more enjoyable and believable to play in.

The darker take on Batman and Catwoman  (more fictional in presentation than represented in Nolan's films, but still with a more realistic, gritty look than usual comics) is what i also like much in the game. Their appearances I think are perfect for a Batman franchise, and this game being the only contender to better Nolan's masterpiece trilogy.
