My most important advice for all worldbuilders

Pretty simple, but if you worldbuild for an rpg, don't bring your world into your campaign before you are done. I've been worldbuilding for almost a year now. I started my campaign when the world was 3 months old, because I thought that it would help me to build it. Turns out I was wrong. If you want to be a good campaign master, you will have to move your world around. I tried to commit to everything I said, because this is mostly an improv show, but it simply doesn't work. But because you have already said this and that about your world, you will bring your world out of balance if you want to get a little bit creative with your campaign.<br><br>For example, I have a forest filled with faeries, and if the players say "This is dangerous, let's go around it", I will have to come up with a good reason to go there anyway. This will always come at the cost of the world, and can never be good if you want to build a world that is realistic in some way.<br><br>I can't even imagine how hard it would be to bring a world in a book or something in it, because then you can't change anything anymore, which makes it even harder if you started with an unfinished world.<br><br>Tl;dr: Don't bring your world in a story before you are done with it.
