Hey Alfred! Have you checked out DayDreamer/DayDreamUniversal? It’s very similar to this! In Daydreamer/DDU you create “tags” for you PC and those act as your “rolls”
“Games You Can Play In Your Head By Yourself” is also worth a look.
Thanks for your comment! Yes, I’m familiar with those (and I love my GYCPIYHBY book!), but for whatever reason they don’t completely click with me.
