Remember the X-Com series? The Earth defense against the alien horde? Well it's all the rage again. Just this time it's free software and culture: GPL and Creative Commons. There is a strategic component and a tactical shooter. Sure it's a work in progress but it's getting there.

The biggest problem was the selection of the quake 2 engine which relied on prebaked bsp files for terrain.
That has been biting them in the ass for years.
Get some people to volunteer to rewrite it on top of openscenegraph with bullet physics and maybe voxelized space handling the terrain deformation and you should be able to support every system ufo:ai still supports (pretty sure it requires GL 2.1+ nowadays due to shaders and such, correct me if I'm wrong) plus new systems up to the OGL limits before switching to vulkan.
