@horrorhound said in As an ST..:
..as an ST, how do you balance for yourself, your group, your sphere, your game, the stories that are on a grand-scale vs. personal?
Usually when a story is set to be personal it starts out that way. A pack wants something ran, for example, so there isn't that much need to balance it out; they are the stars. At that point it's pretty similar to being a table-top DM/ST, with the main difference being you can't blow up the city in the process.
Otherwise my PrP series are launched from a neutral place exactly so that I can fit personal storytelling in them later on. That's tricky - and potentially unwanted - to plan for; sometimes characters I want to buy in don't, and others I didn't expected show up big time. There's no control over this since OOC factors play in the mix (RL schedules, players already having too much on their plate, etc) so I read the room and respond accordingly.
So to answer the OP's question I balance things dynamically because there's no one-size-fits-all approach here. Stories just need to stay flexible to accommodate newcomers, emerging ideas and approaches, even for interactions with other plots ran at the same time.
The one thing that isn't flexible is my own time. I have what I have, and I'm available when I'm available. Everything else has to work based on that or else it won't work at all, so my responsibility here is to make it clear from the start and stick to it as much as life allows.
