Really enjoying it so far. A few nice twists in order to account for sub tech units vs phc units (avatar vs incursion as example) changed the mission flow a but and required changing stategy, which was nice.
Definitely will help people unfamiliar with substrate learn the basic capabilities and some strategy which only improves the new player curve if they play the singel player as phc and substrate they have a much better understanding of what to expect going into multiplayer.
All around an excellent addition. Would be great if Stardock could officially incorporate this as there are a few minor inconsistencies that I don't think can be fixed through the mod. Mostly with the campaign cuts cents and voice overs that reference phc units/abilities. Not sure you can mod those 
Cheers to you Agent Orange and keep up the great modding! Looking forward to more of your work.
