Wrong franchise
I'm waiting for the MegaTen franchise to try and get in on this - then you can really wander around trying to capture the Whore of Babylon (http://megamitensei.wikia.com/wiki/Harlot). A friend asked if I was playing PG, and I said the same thing - I'd really be into a SMT version, wandering into rivers in search of demons.
He said there's already a game like that out, called 'scopolamine.'
