When I think of extreme worldbuilding, I think of J.R.R Tolkien's entire setting and works like Yoshiki Tanaka's Legend of Galactic Heroes. From both of these diametrically opposed settings, my ideal exists as a world as in deep culture as Tolkien and as rich in society and history as Tanaka. This has sort of run amok in my instance, but just how much is too much? When do you draw the line or simply stop being able to care or follow? The reason I ask is because in my current setting seems impossible to split out or summarize. The differences to the real world are so great that I think a info-dump of several thousand words would be necessary to explain the setting and culture. No matter what I do, I think any reader would be so overwhelmed and confused that even my best introduction will be taken as utter gibberish. I do not exactly want to explain how deep some of this "worldbuilding" goes, since I am kind of afraid of the looks I'll get about this. So if you could entertain me with your notions of "how much is too much" or when you simply stop caring about the setting. Please, it would be very helpful as a baseline assessment.
