Chase, the one addendum I would add is that there be a cap on the number of games played.
I.E. If someone hold a territory that is bordered by many other territories. I didn't see anything to say that a player in each territory next to it couldn't try to take it in the same week. In other words forcing the defending player to play MANY games in one week.
I had this happen to me in a mighty empires league for fantasy, where I had to play NINE games in one week or forfeit any game I didn't play.
If only one person is allowed to assault a territory at once, disregard this message.
