this games stuff is so good its crying out for a sandbox Smiley
and multiplayer!!
kickstart, hire a network programmer, build, sell , profit!
youd probably surpass a million dollars on KS with the popularity of SF and what you can show with it right now, especially if you released a demo or something.
I know youve said a KS campaign is a big deal and time consuming, it is. But look at Star citizen, you are very similar to him in that you have accomplished a lot already before your kick starter, have a lot to show for it, not just concept art. Your fan base is already there, its a recipe for success. Set a modest goal of 100k if you like, but watch it expand with stretch goals.
Take a month off from dev, and market it on KS, the game might gain far more in the end.
just want to help, thanks,
