Eh... I would not have gone with Tradition. Aristocracy is good for wonders, but I don't imagine that'll be the focus of this game. Monarchy will be good for even cheaper land buying, but you're already fairly boxed in, and you get the culture of whatever cities you conquer. Monarchy is also 3 policies into the Tradition tree. That's expensive.
The more policies you get, the more expensive they get. After your first few, you'll find it'll get longer and longer between them unless you
really concentrate on culture. I would have gone Liberty, as every policy helps with expansion. Oh, well. Having a King Washington should be an interesting touch. (King is the title your leader gets with Tradition, right? All I can remember now is Consul is Honor, and Lord is Piety).
Oh, and the ideal spot for your second city is right below those horses. It'll have good resources within it's initial donut, and it can expand to even get the sea resource on the other side.
Can't wait to see how this RPC goes.
