I've designed a lot of solo TTRPGs at this point, and there's a fair chance that not many of them are fun. I started to think about what makes a solo TTRPG fun.

Here's a list of things that might make solo TTRPGs fun. Do others come to mind for you?

• A setting that you find interesting
• Variety, so that you cannot predict what will happen next
• A sense that you have a choice about/some control over what will happen next
• Mechanics that don't mean you need to keep a lot of numbers in your head, or do lots of maths
• Combat that allows you to be strategic if you want
• The thrill of a lucky roll, and the dread of an unlucky roll
