MultiworldGG

What it is
MultiworldGG is a multi-game randomizer that joins supported games in one multiplayer session. An item found in one player’s game can be assigned to another player, and supported games can also be generated as single-player experiences. The project is a fork of Archipelago, with tweaks and additional third-party worlds. Players can generate locally with the desktop client or use the website by uploading YAML configuration files or ZIP archives. Lobbies let participants upload configurations and coordinate in chat before a host generates the multiworld. Hosts can upload a generated ZIP or multidata file and provide trackers and patch-file downloads. Installations include a launcher, generator, server, and some clients; desktop downloads are available for Windows, Mac, and Linux. The website also links tools such as a text client, checklist tracker, and manual world client. Website-generated multiplayer games are limited to 30 players; larger games must be generated locally. Many catalog worlds are still in development and may be buggy or unfinished. MultiworldGG is free and open source.
