 - **CC0** — safest default for closed-source games; attribution not required
 - **CC-BY** — commercial OK; keep credits
 - **CC-BY-SA** — commercial OK with caveats; prefer extractable asset bundles over encrypting SA files into the binary
+- **CC-*-ND** — generally **unusable in games** (interactive sync/remix = derivative)
 - **SIL OFL** — preferred for fonts embedded in games
-- **Marketplace “free”** (Unity / Fab / Unreal / many itch packs) — engine or pack EULA applies; do not rehost
-- **Trust the supplier** — anonymous “CC0” mega-dumps can be license-laundered rips; prefer known creators and keep a paper trail
+- **ODbL / OSM** — game binary usually OK as a Produced Work; credit OSM; watch redistributed geodata
+- **Marketplace “free”** (Unity / Fab / Unreal) — often commercial in-engine, no redistribution, sometimes engine-locked
+- **Trust the supplier** — skip anonymous mega-dumps and known traps (MB-Lab, default Shadertoy, Maps scrapes)
