Spring RTS Engine

In this game:

Which is a nice game and i am proud to be the contributor of the sounds, you can find lots of buildings. Everything is GPL, i think. With some handling i think most buildings can be reused for Spring.

Also, it would be a nice touch to fight among the ruins of an old Lincity city...

Unlike Warzone 2100 this game uses blender for the models.
It's possible to export it to Spring.
People do need to understand this is GNU GPL material!
You can't just freely incorporate it inside your non GPL mod.
