So that one sentence from @Mitokandria says a lot more than 'it's a gameplay overhaul'. You should explain what it overhauls, what its purpose is. Is it harder than vanilla, more realistic,....
I also wondered if it's compatible with exististing mods, but I suspect it is.
But, I have to say, I understand what you want to achieve a lot better now, thanks @KSRe-dev!
Edit: still, some kind of explanation/manual will be necessary when you go live, I think. Keep up the good work!
