This is a fascinating analysis! The Preparism axis really resonates — I think a lot of GMs fall somewhere in the middle, wanting structure but needing flexibility when players inevitably go off-script. The pairing of Directorism and Egalitarianism is interesting too, as those feel like the axes that most define different play cultures (OSR vs. storygames, etc.).

This is a really charming concept — solo RPGs with minimal components are such an underrated niche. The notebook-and-pencil constraint is actually a great design challenge. Good luck with the playtesting! Curious how the spellcasting system develops.
