Which multi-agent or multiplayer generative world models can I actually download or run, and what do the repositories and model cards say about their licences?

Of eight multi-agent world-model papers inspected, Solaris (two-player Minecraft) ships code, evaluation data, training data and weights under Apache-2.0 per its repository and card. Gamma-World ships Apache-2.0 code and .safetensors checkpoints, but its model card states no licence. MultiWorld states code Apache-2.0 and data/weights CC BY-NC 4.0. MIRA releases code and a gated CC BY-NC-SA dataset but advertises no weights in the text read. MetaWorld releases only single-person code. No release was found for MASS, WorldCast or ShareVerse. Curator qualifications: Excerpted evidence located (one excerpt-less row); release status/licences per repos (Solaris Apache-2.0 code/data/weights; Gamma-World Apache-2.0 code + safetensors). Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary. Limitations: [component_reuse_restriction] Licence labels per repos/cards; not re-read as full texts. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
