@lowdownfool The author(s) only mention D&D, Sorcerer, and Elfs as inspiration. I've played it with people IRL and it very much makes the players contributors to in-session worldbuilding. So much so that I had to start pulling back on pre-designing too much detail into the scenarios that PCs were confronted with. After a few extra successes on their "tests", they start to define facts in the game-world. I felt like this was actually inviting me as the GM into the gameplay in a very active way.
