You basically go back and forth between a first person game where creepy shit happens and a haunted Dragon Quest clone full of glitchy graphics and people saying creepy shit.

Hmm, that's a little more overt than I would like, but that's still a really cool idea.
There's another game that does something similar without letting on up front what you're getting into - or at least, pulls a cool bait and switch - but talking about it is hard because it then becomes a massive spoiler.
