Lately I've been using solo play tools more and more in my prep. For example instead of just pulling a town out of my imagination or from a bunch of tools. I've (mainly) used Ironsworn to solo play some episodes in that town. Creating details about it as I've gone along. Also used Artefact (more of a journaling game) with good effect to create legendary items. To get into the Glorantha setting, get into the "right" mindset, the solo choose-you-own-adventure I've found great.
But I'm always looking for new tools to, if nothing else, get new perspectives on things. My default Ironsworn is leaning kinda heavily into more perilous and grim episodes.
Happy for any and all recommendations!
Scarlet Heroes has some nice solo tables. The Tome of Adventure Design is also pretty nice for random tables.
Scarlet heroes sounds interesting. I'll put it on the "shortlist". The tome on the other hand... I have plenty of tables. But then mire is better. By its drivethrough description it appears questing beast did some reviewing of it.
