So I'm playing Rome for the first time this fine Saturday and something really odd-seeming is happening. The Seleucids have allied with Egypt and they've both been at war with Carthage for about the last 100 years give or take. Much of the time all of Carthage has been occupied, but it just never ends. Maybe the Seleucids want to occupy it all themselves? Is this a somewhat regular occurrence or a very strange game?
