For our next settler I suggest the green tile between Bentley & Roosting tree near the Indian border. This has the potential to be an immediately productive city, and we need production now, IMO.
For this reason I'd eliminate the tundra spots until later; they are basically fishing villages, & under the Conquests city ranking system wouldn't it be a disadvantage to settle them too soon? Or is that not an issue?
For our second settler I'd either take the northern spot close to the iron or more likely the pink/purple spot close to Groningen, but I'd settle one tile south. There would be little corruption in the Groningen spot, and more production. At the moment production is king.
I do hope we're not going to poll each settlement site; remember, we're going to need at least 100 cities (though we'll capture many). That's a lot of polling. I'd prefer we be presented with a general plan and vote that up or down on its merits, and let our officials micromanage exact settlement locations.
