I am gonna tout Mike Shea's "Return of the Lazy DM" @SlyFlourish , got a website an all, tons of advice on low prep rpgs
The "bring one piece of content" failed utterly.Nobody was willing to do any homework outside of game night.
If I were to do it again, I'd lean into the "players create the content at the table" aspect. Microscope worked really really well. I'm not sure how it would work, though—creating NPCs, encounters, maps at the table? I think it's more common in rules-lite games, but my players prefer 5e. But it does seem like there's some potential there for a truly low-prep approach.
I tried this with NPC names. Each player was responsible for one race (the race of their character), and was supposed to bring a list of names for that race. I shared some random name generators I had googled. Then, when they encountered an NPC, I would ask them to name them.Asking players to come up with things at the table is the way to go. Simply by being there they are in the right mindset to create. Even asking players pointed questions at the end of the session gives you ideas of what to focus on in the next one.
I’d love to hear more ideas about doing prep “at the table,” with players’ involvement, à la Microscope. It didn’t really work for me with NPCs but I feel like it could work if I had the right mini-game to use. (Again, like using Microscope as a world-generation mini-game.)
