They beauty of having a world you invented is that as long as it's not officially published, you can change it.
I have been looking on and off at my notes for the last few days for my first game, and at first I thought I wanted to just organize the notes in a different way. Something wasn't right, something was off about how I began this... did I just have to retype it in a different format?
Nope, upon further inspection I just realized I had done some silly stuff as "DM porn", where there was a character I was definitely excited to introduce to the PCs, but definitely introduced way too early. Other structure things... including long times of boring where I was like "Here's a place where you can do stuff!", not realizing that PCs are usually pretty good at letting you know when they're doing something without being given a gap.
Unfortunately only experience would teach me about that stuff. It'll be interesting as I go on and rewrite this to have it make more sense. However, the big events are going to stay the same. I'm not telling anybody those yet, who knows what future players may be reading...
