Play this game blind, it is worth it, their story is worth it, I only ache that the end is where it was, but this is the most emotionally provoking game. At first I didn't like the characters, there was nothing to them, but as they became more defined, they became more amiable, and by the end of it, I found myself so attached I didn't want to let them go.
I hope the promise was kept, they deserve that much, at the very least.
