I'll need to do a second read of this for a more detailed critique, but for now I will say that this is an impressive expansion on DoW's mechanics. The scope feels like it would fit best in an asynchronous digital format or a game over Discord. It would take a lot of coordination to make a live face-to-face run of this work considering the mechanical complexity and projected player count. If you are going in that direction, you could consider paring down the number of teams or slightly streamlining some mechanics, like the New Eden edition of DoW.
