Thought it was fantastic but just incredibly repetitive.
Graphics and free run were a standout. BUt over time (i completed ALOT of it) it got really boring and repetitive.
It's one of these games you pick up again after a few months, love it, then realize why you stopped playing it.
Defo worth renting it for the story.
Like FE said, if they sort out a good few areas of the game the sequel could easily be one of the best games of all time.
