So, out of curiosity, if one wanted to use the ambiguously- or non-licensed art assets from Zero-K for a non-related (free/open source) game, what would be the recommended approach to avoid incurring the scorn of devs and community?
* Treat everything as PD and just copy/use whatever.
* Require an installed copy of Zero-K, and use the files from that location.
* Manually or automatically copying files from Zero-K repositories during installation.
First seems rather questionable, and presumably will not win any popularity contests. Second option is certainly legal and is used for many open source game-engine rewrites using original assets. The third option is legally the same as the second, but feels a bit dirtier, especially with automated download since it gives very little exposure for the source of the assets. Attributing assets is a given in all cases.
Any thoughts?
