Yeah, there's going to be a lot of gold from these improvements, alright:
I'm going to build a dotmap in stages, I think. First city site thought:
This site would be pretty decent early with pigs and several hills (needs AH and Mining, obviously), and grow to be a real monster once I get culture and a Temple of the Hand here.
Biggest downside: nothing in this city works early game. No overlap with capital, need at least four techs beyond Calendar for its full potential. I'm debating if it makes sense to move it closer, or just to make it the fifth city and settle in other directions first.
A potential candidate for earlier settlement is something more like Strawberry here:
Shares two grassland riverside tiles with Vanilla, as well as a forested hamlet and Banana - can grow pretty well with only Calendar researched. Obviously it improves with Mining and a culture source, but those aren't really required.
I feel like this isn't the best site, but it could work decently as city 2.
This is the throw ideas at the wall stage of dotmapping, just to make me start thinking and give my loyal dedlurkers something to look at. I'm definitely not married to either site, I just don't see anything obvious. We've got a lot of time yet before settler production will start.
