MultiworldGG
What it is
MultiworldGG is an open-source game randomizer that links different supported games in one multiplayer experience, allowing an item found in one game to belong to someone playing another. It can also generate single-player experiences. The project is a fork of Archipelago with changes and additional third-party worlds. Players can generate worlds locally with desktop software or use the website by uploading YAML configuration files or ZIP archives. Lobbies let participants upload configurations and chat before a host generates the shared game. Hosts can upload a generated ZIP or multidata file and provide trackers and patch downloads. Desktop downloads are available for Windows, Mac, and Linux; installations include a launcher, generator, server, and some clients. Website-generated multiplayer games have a 30-player maximum, so larger groups need local generation. The supported-games catalog warns that many worlds remain in development and may be buggy or unfinished. Custom APWorld files can run code on a user's computer, so the project recommends checking that their source is safe and trustworthy.
For and against
For
- Connects items across different supported games.
- Supports both multiplayer and single-player generation.
- Offers web and local generation options.
- Desktop downloads are available for Windows, Mac, and Linux.
Against
- Website-generated multiplayer games are limited to 30 players.
- Many game worlds may be unfinished or buggy.
- Custom APWorld files can run code on the computer.
- Some games are incompatible with Mac client libraries.
The verdict
MultiworldGG provides several ways to configure and host randomized game sessions, including local generation for groups above the web limit. The development status of some worlds and the code-execution risk of custom APWorld files merit attention.
Who it suits
MultiworldGG may suit players who want randomized cross-game multiplayer sessions or single-player generation. It also offers configuration sharing, lobbies, and local generation for groups that need more than the website's player limit.
