I'm fully sighted, but the concept of visual free or visual agnostic games has been something I've wondered about for a while. I hadn't considered the viability of heavily menu based RPGs before, but reading about it, it seems plainly obvious (kind of embarrassed I'd never considered that). I really want to see (or find time to make myself) a first person game with no visuals and all the gameplay feedback through binaural audio, but I'm not sure of the technical details necessary for the audio part, and I have no idea how playable such a game would necessarily be.
