Being "well known" doesn't translate into people knowing how good it is.
I knew of UFO AI long before I decided to give it a spin. I was so sick of UFO remakes that petered out halfway, and I had so many better things to do (or so I thought)...
I dare say the same is true for many jaded UFO fans waiting for the next "reimagination" (Firaxis)... UFO AI? What's that? Why should I try it?
It didn't help that the first few installs crashed on my MBP (except in bootcamp) and 2.3x dev had mysterious crashes to desktop on a fairly frequent basis - I junked it the first time it happened, and came back several months later to try another build.
The guys on ta universe don't seem to know about UFO AI.
The guys here
http://zero-k.info/Forum/Thread/2271 seem to remember X com, but don't mention UFO AI.
It might be worth your while to get out there into forums and make yourselves known. I think the latest 2.4 stable release is a fairly stable, very polished platform for showcasing what you guys have done, and can do, and will attract more people to help since it's clearly more than one of the "fall-by-the-wayside" remakes.
