What MultiworldGG is
MultiworldGG is an open-source randomizer that connects different supported games into one multiplayer experience, where an item found in one game can belong to someone playing another. It can also generate single-player experiences. The project is a fork of Archipelago with adjustments and additional third-party worlds. Players can generate worlds locally with the desktop client or use the website by uploading YAML configurations or ZIP archives. Lobbies let participants upload configurations and chat while they coordinate; a host generates the multiworld when the group is ready. Hosts can upload a generated ZIP or multidata file and provide trackers and patch downloads. Desktop downloads are available for Windows, Mac, and Linux, and installations include a launcher, generator, server, and some clients. Website-generated multiplayer games allow up to 30 players; larger games need local generation. The game catalog warns that many worlds remain in development and may be buggy or unfinished. Custom APWorld files can execute code on a user's computer, so their source should be checked before use.
