Before the lumber mill change, flat land cities were good as dead and worthless. After the lumber mill change, i noticed flatland and hills make no difference anymore. Whether a city was mega awesome or craptacular was entirely dependent on how many rainforests and forests there were. Once I got like 5-10 lumber mills on a city not only does it grow really fast but its production power rivals my capital. So I'm thinking, never chop and go 100% mill forever. But I'm still seeing people say chop chop chop. chop wonders. chop settlers. chop chop. Isn't lumber mills better? Isn't having a city as strong as the capitol better than a worthless city?
