I posted this over on the clientclub group just before we moved over to Skool. This is a copy/paste job - Sorry if it's not acceptable to repost this way, and feel free to delete it if reposts like this aren't acceptable:
Has anyone used an oracle like Mythic to "practice" GMing or warm up before presenting a campaign to your group? If so, have you found any benefits from using them?
Most of the "solo" campaigns I have tried are more "Choose Your Own Adventure" with extra customizability than a true TTRPG experience. However, solo game systems like "Thousand Year Old Vampire" seem to get my creative juices flowing in ways traditional brainstorming doesn't. Do you find any benefit from using solo systems as a GM warmup? Why or why not?
