Just be aware that even though they’re free, we still have to comply with their EULA for the animations/characters we download/“purchase”, which means we may NOT re-distributed in ie. fbx format for various marketplace content (only in a packaged executable game or similar), which kinda sux, but still makes pretty good sense if you think about it.
