I'm not sure.  The other two roleplays that I'm involved in are a slice-of-life romance and a fantasy one.  I was looking at a fighter pilot one with some cool ideas but it seems to have stalled out and that doesn't speak well for the players involved.  I'll have to look around.  Maybe you should try bumping and upgrading the interest check and maybe add interest checks in other areas in case somebody is looking for a change?
