If we're still pulling in concepts, I'd love to see a horror title that is sort of a mash between Miasmata and Galerians (minus the combat). You wake up in an abandoned research facility suffering from some sort of degenerative psychic disorder that gets progressively worse over time, and it's your task to get through the various rooms of this lab to both cure your illness and escape alive. This is complicated by a need to suppress your erratic psychic abilities that threaten to overwhelm you (and maybe the smaller outbursts could cause slight annoyances like a power short in a specific room or something), as well as avoid, divert, hide from, and temporarily ensnare another, less human, subject that managed to be the only other survivor. I have some ideas for situations and mechanics, but that's the gist of it.
Just a thought, anyway. Regardless of the final project, I'm game to help out with concepts and maybe some coding depending on what software is used.
