it would seem that it would be easy to do a scenario like that. but its not because someone always ends out complaining that something and something is too strong and why arent there 3 phases and when i once tried to fix that I heard "how come they can shoot in the assault phase." then I gave up on it. In case you were wondering, I had SM, Nids, Necrons, and Eldar in there. Necrons just filled up remaining terran and protoss slots. I had some left over, too.
