It'd be too easy to get stuck on a wall or a character though if you ask me. I suppose if you spent long enough stumbling around aimlessly trying to find your way you'd be able to get somewhere, but I don't think you could do it without help. Once you need to start developing your characters on the sphere grid you'd be screwed. I don't care how awesome this blind man is, they're not going to be able to effectively navigate that many menu screens without help.
