It's not about making a mod for myself anymore and share it, working with the community to improve it, it's about how do i best sell my stuff.
Only if you choose. That's the point. You don't have to make a mod that will be popular enough to sell, and you don't have to sell it even if it is. If you can afford the time to make and a release a mod for free, then you can just do that.
The only time making a mod must become about "how do i best sell my stuff" is when you can only afford to make it at all if you sell it. In which case I'd strongly advise you not to waste your scarce time and effort making mods, because the chances you'll make enough money from it to justify the time and effort is vanishingly small.
Mod making is one of those ultra-borderline commercial/artistic efforts like freelance art. Or creating webcomics. If you're doing it as a hobby, you can carry on doing it just as a hobby. If you expect to maximise your income from it, and focus your efforts on doing so... well, don't give up the day job, because you'll probably fail.
But choosing to make a mod the way you like, and then charging a small price for it, doesn't mean you can't share tips and help and be supportive of other modders, or work with the community to make your own mod/s better.
