On the subject of the Moors and Iberia...
In the picture, I moved the sheep 1N and the wine 1E, and I edited the river to make it more geographically accurate and allow Madrid to still be next to it.
Currently, Spain spawns in 720 AD one tile south of the Madrid labeled in the picture. However, the most important Islamic city in Spain was Cordoba, which can't exist at the same time as the current spawn city for Spain. Instead, Spain should either:
A.) Start in 720 AD at Ovideo or Leon, to represent the Kingdom of Asturias/Kingdom of Leon. This would require a small or non-existent flip zone, the 1N Madrid being an Independent city at the start of the 600 AD scenario, and the capital to be programmed to flip to Madrid on capture.
B.) Start in 1080 AD at the Madrid labeled, to represent Madrid and Toledo being retaken by the Kingdom of Castile. The flip zone would be everything north of Cordoba (On the Iberian peninsula, of course.)
Also, at the start of the 600 AD scenario, Corduba should be an independent city, and we need to figure out a way to have Islam spread to the Spanish cities controled by the Moors. Maybe they could start with Islamic missionaries?
