I noticed that there are a lot of civ2 graphics on these pages, but I can't find a license. Evidently some of them must be license compatible with Freeciv, as much of Amplio and Amplio2 is based on them. Does anyone know if it is okay to use these for Freeciv, if not for the main distribution, then for mod-packs? (I am not on civfanatics or I would ask there myself)

For those that are in freeciv (as in freeciv.org, I don't speak for what forks have done), authors were explicitly asked to relicense (or "dual license") them for freeciv use (GPL2+).

I knew that. I meant that if the authors released some of their work for freeciv, maybe someone could compile a library of their units that can be used for modpacks and stuff.

Another possible source of graphics is opengeneral. They use oriented unit graphics similar to cimpletoon.
