After fiddling with the Egypt maps a little bit more, I've decided to change the settings for each map around to best suit the map. It will still be Sequential play, Unlimited forts, but the cards for each map will be as follows:
Lower Egypt: Escalating Upper Egypt: No Cards Nubian Egypt: ??? (I'll edit this when I play the map upon release) Valley of the Kings: Escalating
Since interest in this tournament has decreased a significant amount, I'm further editing the setup to 32 people, with the top 2 from the first round advancing to the second. People help me out by finding just 5 more.
