Here's a related software that I like : https://archipelago.gg/

This is a multi-game randomizer, where items will be scattered accross all games in the multiworld, and so players will have to find items in their own games, but for eachother.

It's really fun, and I am just amazed by the fact that it works so well for a ton of games.

It's so awesome! I want to finish adding the Ultima 6 one sometime - https://arya-iwakura.github.io/Ultima6Randomizer/
