Do the colleges currently serve a purpose in the game? I haven't noticed any effects between leaving my new family members in the backwater ends of the empire and sending them to rome to learn in the... highest form of school.

Do hippodromes add a happiness bonus that isn't listed in the description?

Is there any recommended tax setting? Even on low I'm having problems keeping people happy, and I thought the one that balanced it all out was high?

Is there any factors that can cause a lot of unrest? One town doesn't have many health problems, and its only a short distance from the capital, but it has huge unrest problems.

Seems like there was more questions but I guess they weren't important.
