How much do you prep for a Solo game?
When you play a game of a solo game, and let's use ironsworn as an example, how much do you prep for it before hand? Being new to ttrpg and Solo play, I don't really know how to prep for it. It seems to me that every game requires generating characters and NPCs and locations and goals (aka plot). I can see scenarios that could utilize pre used elements or ones that were generated for previous games and just using them over again as needed.
I get it, just because it's a solo game that's greatly managed by an oracle, it doesn't mean that there's no game master. The player also has to be a game master and part of the role of the GM is to build the game.
But what if I have an evening to kill and I wanted to play a quick game and I'm starting from scratch? I foresee spending an hour or more preparing before I can even start playing.
Maybe there are better solo games for quickie simple play sessions? Or maybe I should spend some time spinning some pre made elements that I can draw on for a quick game?
