Let's try to cram #HTTRPG #AdventureDesign into one toot. The Duke Meany examples demonstrate a simple idea: Some facts constrict the viable range of PC approaches; some facts expand/multiply that range. In this context, we likey multiply-ey.
The Duke Meany examples have just six supporting notes each, which is enough for a seed but not quite enough to call a ready-to-run scenario.
But 30-90 well-designed notes? Solid one-nighter. Make it something the PCs will be passionate about.
