Yeah, being a fan of worldbuilding is tough! Especially if you do the research, you eventually hit the point where you start noticing all the places where other authors didn't do the research, and then everything gets even harder.

I'm hoping there's a point where you get over the hill and back to where you're willing to go 'fuck it' and know which research is really vital and which you can skip, but I'm not there yet (especially for identity- and culture- based stuff; in the hard sciences I am at least to the point where I'm more likely to go 'that's not weird enough yet, there's weirder stuff on Earth' than to nitpick the science.)
