After the first episode, when you setup the basic city layout, the episodes are simplistic and can be finished quickly. I didn't receive a single invasion and I was playing at olympian level, so have no idea what the first commenter was doing. There arn't any invasions or favor decreases scripted.
OK, I guess, for quick easy episodes.
There are few scripts and the goals are quickly finished.
Map Design: 2
The Empire Map has a trade route error for Apollonia(ally) which gives the illusion that Cydonia is trading and Apollonia trade has been shutdown.
The Map itself was too artificial looking with the right angle land/water areas.
The 2 monsters points were isolated from the city area, totally negating the danger/challenge factors.
Too much information. Little storyline.
