Must buy game. It's not necessarily a game though, it's more like a story and you progress by the decisions and dialogue that you choose. The story's based on a franchise by one of DC Comics' child companies. You play as the Big Bad Wolf (Bigby Wolf) in his human form who is the sheriff of Fabletown (a secret civilization within NYC) investigating the town's first ever murder. Many other fairy tale characters such as Snow White and Mr. Toad appear in the game but the setting is very dark and modern.
If you've played The Walking Dead, then TWAU is totally worth playing. I actually recommend both, but so far TWAU feels a lot longer.
