The Land and the People uses the Carta SRD brilliantly - as a foundation for a game about making maps. The writing prompts set their scenes well with in-universe conversations or events to work from. I find this game a lot lower stress than many - your in-game persona is never under any kind of physical threat. This one sparked a lot of thoughtful writing for me, and I very much enjoyed playing it!
A Day at the Crystal Market has a low-stress victory condition built right in - "You might not get everything your mentor wanted you to get at the market, but they won't mind." This lets you focus on the beautiful moments that come from the writing prompts. A very chill experience!
