If I exclude the lake and three mountain tiles, I get 14 tiles to work with within my second ring. That's perfect for a 10 pop city since 10 workable tiles + 4 special districts, which makes me think maybe I should place my second city 4 tiles away to prevent overlap. But that's when only thinking about the final state and in the process of getting there a lot of tiles will be left unworked. This makes me question, when considering overall gameplay, is it actually better to aim for an end state of a city with few inefficient specialists or maybe even limiting population to something below 10? Since in the end, what matters is how much you've produce throughout the game and not how much you can produce per turn right before the game ends. Thoughts?
