Could Re-volt possibly be ported?
The source code was released some time ago, and these people updated it to OpenGL and to work on more recent windows versions and the like.
Stretching it a little, maybe allow MP to work between PC and Vita? (Uses Client/server architecture)
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
