There have been some thoughts as well about the indigenous races, maybe there wont be pirates as such, but heretics will have small fleets, and Kroot will protect their homeworlds. But Kroot will also eventually be playable with Tau in a much later release of this mod.
Its going to be a lot of work, but we would like to keep hearing suggestions and we will include as many of the good ones as we can.
Thanks for you quesiton and congratulations on being our first guest
