I've decided to go ahead and develop the ground side. This is a big decision though, since I tend to do 95% of the modeling. I've also picked up 2 new modelers recently from the moddb community. I've assigned them some work and hopefully they will work out. If they do, things will go much smoother.
I'm going to do a few more proof of concept models for the ground and see where it leads. However I had originally wanted to release another version of the space mod before the new year but since I'm starting up the land development again, that will be put on hold until I have a substantial land part to go along with it. That and the fact I have never modded the ground battles, infantry, etc, before means it will take longer than before.
So, that is where the mod stands currently.
