As was said elsewhere, there's always willing participants but very few people willing and capable of taking on the work and responsibility involved!
I think what is out there is dependent on who is willing and able to work, and what they are interested in, not a lack of interest in general.
I am working of a Fading Suns game for someday but it will be awhile. I bet there are other games that are being worked on too! Ask around, if you have the time/inclination you might be able to help!
