last I heard the league was going to use the mighty empires simple rules. It will start off with games at 750 points and go up from there. As far as tile control, the winner will be the person with the most squares at the end. Also the tiles with mines will give you gold every turn, this will be spent on different things.
From what I understand as it stands now a turn will consist of a player challenging another player (this does not have to be someone adjacent to them) the two players fight the winner and loser will both receive empire points based on how they did. The empire points are then used to take control of tiles and build mines or castles on them. Rinse and repeat for next turn.
