He left for the island without his bottom? That's gonna be problematic.
Well it's not a new take on gaming. MYST was essentially the same concept - a story told in the context of exploration and discovery. It looks nice, and interactive novels definitely have that great aspect of interactivity that a written novel could never have (unless you're tucked away in a school attic reading The Neverending Story). As far as art goes, I don't see it being that much different to other games, with the exception that you're basically gonna be a witness to a story - kinda like a movie. Yeah, movies are art, but this game doesn't exactly elevate it to a whole new idea of art.
Looks interesting enough though. If it conveys the same atmosphere the trailer did, it'll be nice and spooky too.
