Microscope is one of those games that is easier to play solo than most RPGs that were not meant to do that, when you use it just like your creative writing exercise quide. And somebody even made a nice app - https://utgars-chronicles.app/ if you happen to have easier time tempting your internet-friends than your irl friends.

Another fun thing to try with the irl group, if like having longer campaigns, is to start with a session of microscope first and then play in the world you scoped out :)
