The Persona series isn't really all that niche, compared to the rest of the games in this thread anyways (though perhaps Persona combined with Etrian Odyssey is a bit more niche), but I didn't know where else to put this.
Wow, just wow. Such an awesome limited edition. This will run for $80, and of course in usual Atlus style, we'll get a first print run edition. The first print run costs $50 and comes with the tarot cards like the premium edition, and a fancy box. Only the premium edition gets a soundtrack unfortunately.
