How was the multi-player training data in these papers obtained (bots, simulators, game recordings, single-view video), and what does each source imply about generalising to human play and about rights?

Five data routes appear: scripted Mineflayer bots in Minecraft (Solaris, Gamma-World), publicly available bots in Rocket League (MIRA), a driving simulator (ShareVerse, CARLA), recordings of a co-op game (MultiWorld, It Takes Two, natural play) and of Counter-Strike 2 matches (WorldCast, OpenCS2; whether players were human is not stated in the passages read), and camera-trajectory unrolling of single-view video (MetaWorld). Authors flag bot-only data as a generalisation gap (Solaris, MIRA). Only MIRA states a publisher permission for its gameplay recordings in the text read. Curator correction 2026-10-24 (discovery audit record C3-B1057-01, curator-reviewed C3R-0688; excerpts re-located by independent curator GET 2026-10-24): Correction. C3-B115-W23-05 says of the datasets other than MIRA, MultiWorld and Solaris that "no dataset release found", and that OpenCS2 provenance and terms were not verified. The Hugging Face card for blanchon/opencs2_dataset (created 2026-05-08, so it already existed when the record was checked) is a public release under cc-by-4.0 that says the demos are mirrored from HLTV and that downstream use is bound by the original tournament terms; so the OpenCS2 recordings are match demos with a stated licence and a stated upstream-terms caveat. Addendum to the MultiWorld licence: the record quotes the repository LICENCE accurately (data under CC BY-NC 4.0), but the dataset card for Haoyuwu/MultiWorldData (created 2026-04-19) declares apache-2.0 and calls the It Takes Two data real human gameplay. Two official pages conflict; neither is marked newer in the text read, so both are preserved: the repository LICENCE says "MultiWorld Data © [2026] by [HKU & Sreal AI] is licensed under Creative Commons Attribution-NonCommercial 4.0 International" (data and model weights), while the dataset card front matter says "license: apache-2.0". Which governs is not resolved here; this is not legal advice. The record was accurate on the repository LICENCE; its MIRA and Solaris licence tags were seen only in Hugging Face API metadata (inference: consistent with the record, gated MIRA card not read). Curator qualifications: All excerpts located; five data routes (bots, simulators, game recordings). 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] Game-recording data rights not inspected. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
