I haven't played this yet, but I will admit that I was surprised on how well done the Telltale games were. I played the Walking Dead (even after my burnout with the IP) and found myself caring about the characters. I also played "The Wolf Among Us" (basically what MS gave for free with Games with Gold on Xbox) and found another tale that was well put together. In both cases they took IP from comics and made a story that didn't overwrite what was in the source while still creating a story that was interesting. I'm sure this Batman is the same.
The only real complaint I have on these games is they're pretty much the same thing. It's more of a "Choose Your Own Adventure" cartoon with some very simple puzzles thrown in to attempt to be a video game. In some cases they did what I really really hate.. Have me control the character just to walk down a hallway so it can kick off the next cut scene. Why I have to walk him a whole 3 feet, and cant do anything else I'll never know.
