Actually I don't understand who/what is the obstacle to hire another few developers so that LFS could be developed faster. I understand that it would imply additional expenses, but ppl buy it, so they could afford at least one or two additional developers. They could find some sponsors at last (if they don't have any yet). This is what I would do.
Anyway, I play only simulators for many years and LFS is the greatest of what I have seen. Also RBR for rally.
