Not the person you asked, but another forever dm who likes it.
I fell into it because I wanted to play and the best way to control scheduling was to run the game.
If you like to write stories that’s wonderful - take a look at some of the pre generated adventures in any system to understand how the different components work in pen and paper games. Just remember that no plot can survive contact with the players unscathed (after all it’s group story telling)- and some level of improve skill will help the overall experience. After that just have fun.
Enterprise tooling (aka a usable API) and it stays out if my way.
