I've been keeping a roughly monthly Shadows of Brimstone game going for years (on TTS during the pandemic, in person before and since) and have had a long time to get setup and space optimized. Minis have clear cases, map tiles also get a flat case per set. All the flat stuff goes into an accordion file case. Cards go into their own case and the specific sets used at any given moment go into a vertical holder. We use character sheets and dials instead of the large character cards, tokens, and smaller cords to keep track of inventory and stats, though there's some things like character abilities that we still use small cards for. As many of the charts as possible are kept electronically. Because I've got about 5 base sets (ice, swamp, fortress, other fortress with conquistadores, other ice with vikings) and a bunch of expansions, it does add up. Over the years, I've are added some nicities including 3d printed token organizers, a deck of cash, poker chips for experience. With all that, it does take two large folding tables for a game with 6 people plus a smaller side table for the stuff that's going to be used but isn't it play yet. Everybody gets a job to do as well, so somebody runs the monsters, somebody hands out cash, somebody takes care of the deck and maps. Storage for all the stuff would take up about 8 cubes in an IKEA shelf thingy. So it's definitely not a small game after all the additions, but my group has gotten it down when it comes to set up, play, and teardown. Usually takes a few hours at a casual pace with lots of food and socializing going on as well. But it did take a bit to get there, both for organization of stuff and the play.

I've wanted to play Shadow of Brimstone ever since I saw the Inside the Box episode about it years ago, but the price, space, setup time and prospect of painting hundreds of minis has kept me off. Maybe I'll look into TTS, it hadn't even crossed my mind.

Awesome, thank you so much for those details! Playing the game solo first (in TTS) is a great idea.
