How do you make, according to /tg/, a good fantasy universe ?

You never finish it.

You don't.
/tg/ isn't a single person. You post it and the people who think it's fine will ignore it and the people who think it sucks will let it be known.
Also teeg at the moment is on a warpath searching for true originality, so you'd have to create a setting with nary a single idea that has been explored beforehand.
Internal consistency
Not OP but...
Post a setting that you think deserve more attention, but somehow not popular.
