Ehhh... I am pretty sure you can't play anything like that here.
You can only play FAF version, or FAF version with mods.
There is a mod that allows you to play with vanilla balance and tryes to simulate it, but i think it was broken in many ways.
Situation with vanilla campaing is better but UI and graphics will still be like FA
Also difference in games not just in new units and buildings, FA is alot different in many aspects and slightly different in all other aspects...
I have not tryed no FA units restriction and i don't beleave it will make commander upgraides just like in vanilla and make t1 mass fabs with 0 mass cost and make all shots fire slower and mobile missile launchers track targets.
Also in last vanilla patches they added t2 bots and mercies to balance, not sure if you ever played with this, but i didn't
Maybe all those things are important only for me, they give me strong noatalgia effect.
