Where does the shared state of a multiplayer world model live, and what are the basic design families the primary papers use to keep several players consistent?
The eight papers fall into four placements of the shared state: inside one joint network (Solaris, MIRA, Gamma-World, ShareVerse) coupled by attention over all views or via hub tokens; in an explicit global state encoder (MultiWorld); in an explicit typed state with separate renderers (MASS); or exchanged between per-player clients as player and scene state (WorldCast). MetaWorld couples two denoising branches by cross-attention at every layer. Which design is better is not settled: papers compare only against their own retrained baselines.

Curator qualifications: All excerpts located; four shared-state placements; cost-driver disagreement (attention vs rendering) kept.
Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
