Should be a piece of cake for AI, just asked:
Let’s build a campaign tailor-made for a retirement home. Light on rules, high on laughter, heroic in spirit.
Setting: The Kingdom of Evergreen Bay. A coastal town where heroes are those who have lived long enough to know better. The Queen has just announced a Grand Jubilee. Unfortunately her magical Crown of Memory has vanished. Without it, she forgets everything every morning. Chaos rises: bakery dragons stealing pastries, mischievous garden gnomes reshuffling street names, a talking cat claiming to be the rightful ruler.
Player characters: Retired legends. A knight with a squeaky prosthetic knee. A wizard whose spells occasionally summon knitting supplies. A rogue who insists every locked door once knew him. Each has a gentle superpower based on life experience: calming frightened creatures, recalling ancient gossip, mending broken hearts or broken chairs.
Main quest: Find the Crown before the Jubilee. Clues lie in familiar, comfy places: the Lighthouse Library (guarded by stubborn seagulls), the Tea-House of Time (where seconds stretch), the Bingo Caves (numbers echo and help solve puzzles). Instead of brutal combat, most problems are solved with clever words, teamwork, or bribing a troll with homemade cookies.
Theme: Growing older = growing powerful. The world needs what elders know.
We can expand with maps, NPC portraits, printed recap sheets each session, even songs if the group wants. The next step is choosing the first scene: the jubilee announcement and the discovery the crown is missing.
