Batman: Arkham City (Collector's Edition)

This game is quite simply amazing.

Right off the bat you'll notice it looks beautiful as developper Rocksteady pushes the Unreal Engine to it's limits by delivering highly detailed character models, a beautiful and lively city with some amazing lighting.
The game features combat, sneaking, small puzzles, riddles, tons of cameos and lots of fanservice for every Batman fan and those who want to find out more about the Dark Knight.
The story and the music in this game rival those of a movie! Kevin Convoy, the person who did the original voice for Batman in the animated series and the first Arkham game returns alongside an incredible last performance from Mark Hamill as the Joker.
This game has tons of content. The main story will keep you around for about 10 hours but then there's still lots of interesting side-missions, riddler trophies to collect and riddler puzzles to beat. If you factor all of that in you'll get around 20+ hours. If that's not enough for you there's still Riddler's revenge which takes you outside of the main campagne and puts your fighting and sneaking skills to the test. And if that's STILL not enough, you'll get the chance to start a game+ after you've beaten it the first time. In game+ you get to play the storymode again but this time you keep all your gadgets and the enemies are a lot tougher.

This game has it all!
