Would love to see mods that increase the darker-scarier feel, to be sure.
As you may have guessed, I'm definitely wishing hard for an Oscuro playthrough and then maybe even an FCOM.
One can dream, eh?
Seriously, though, I'm already trying to see what can be done to port OOO, or at least parts of it. It's not going to be easy, but maybe we can start small and build up as the tools get better.
