My Byzantine migration to Spain is turning out swimmingly -- as I mentioned in a few other threads, it's a tremendously fun way to run the campaign and I encourage any other Byzantine fans to try it out for themselves.

Something I didn't notice when running my earlier Byzantine campaigns: when you get Large Cities with a market, it becomes possible to build public baths. Huge cities can build sewer systems, but only if you have public baths and possibly a fairground. An extra 10% public health bonus may not seem like much, but it comes in right handy during the Plague years with a Mayor's Palace and Huge Cathedral. (That's what, a 40% bonus to public health in total?) Besides, it's fun to look down your nose at the smelly barbarians across the border.
