What do the primary papers leave unshown for collaborative previs or multiplayer games with a generated shared world, according to their own stated limitations and evaluation protocols?
Each paper states a limit that matters for collaborative previs or multiplayer play: Solaris and MIRA lose persistent state beyond the context; Gamma-World may accumulate inconsistencies in long rollouts; MetaWorld does not model physical contact; WorldCast does not model hits or network faults; MultiWorld has not been trained at scale. Beyond these, in the eight papers read no paper reports art-direction or director controls, a multi-human study, or output-use rights for generated clips. The last three are absences in the passages read, not demonstrated impossibilities.

Curator qualifications: All excerpts located; stated limits relevant to collaborative previs (persistence, long-rollout drift, no physical contact).
Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
