I'm running a starfinder one-shot in a few weeks, trying to keep it far far away from dungeon-crawling since I have a similar disdain for them as a player. It will be my first time GM'ing, and I'm nervous! My friends have been pushing me to try it since forever because I'm great at voices and improv, but I'm worried that I don't have a mind for mechanics. I get that feeling, though. If it bothers you, you could always try organizing something outside of the normal sessions? How'd you meet these people, anyway?
It's a student association for role playing games! Usually with really good dms and fun quirky stories since they don't have to be a part of a larger narrative. But it's not the same as having your "own" group. I'm hoping I can get something more regular going with my friends but as of now I haven't had the time.
If you haven't checked out Matt Colville's YouTube series called Running the Game, you're missing out. There's no need to watch it in order; pick and choose the topics that you want to improve on and watch those. TTRPG's are so much richer, fuller, and fun when you tie everything into the settings' world, instead of cardboard cutouts to slash in a row.
