The evaluations are author-run and use different protocols. Matrix-Game 1.0 uses its own GameWorld Score on Minecraft plus a double-blind human comparison against Oasis and MineWorld. Matrix-Game 2.0 reports the same score against YUME on wild scenes and is lower on motion smoothness, object consistency and scenario consistency. Matrix-Game 4.0's report and card give latency and throughput but no image-quality metric, and the card says it claims no benchmark. Hunyuan-GameCraft reports FVD, relative pose error, image quality and a 30-evaluator ranking on 150 images and 12 action signals, compared with camera-control baselines and Matrix-Game 1.0. LingBot-World 1 uses VBench on 100 generated videos over 30 s; LingBot 2.0 relies on comparison figures and an hour-long session. None measures persistence or revisit consistency quantitatively.

Curator qualifications: The Matrix-Game 2.0 claim-vs-table tension is confirmed: on wild scenes it is below YUME on 3 of 6 metrics while the abstract says it 'sets new benchmarks'. That claim may rest on Minecraft or other comparisons, so record it as overclaiming relative to the wild-scene table, not a fabricated number. The MG4 card's explicit no-benchmark statement verifies. Scope: the abstract claim is general; the counter-evidence is the wild-scene Table 2 only. Minecraft-domain comparisons were not re-read.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
