Suede recently did some videos where he called it "bad land Deity" or something like that. It had a patch of mountain tiles near the start. I think the best use of mountain tiles comes as something like the following.
Here's an early Republic screenshot of a German capital still putting out settlers:
6 shields per turn, with 3 more turns to reach size 7. Isn't that low for putting out a settler in time as it reaches size 7?
Here's the governor setting, and I note the "emphasize production" setting as important here:
When the city grows it ends up like this:
Look, we have 5 rows of 3 shields each for 15 total shields on that settler now! Halfway there. So, now the mountain tile gets swapped:
See? Now we'll get the settler while the capital keeps on growing. We also could let all the in range bonus grassland tiles to get used by other cities.
The grassland river cow might seem a little too above average, but once in Republic or Monarchy, grassland tiles can get irrigated. I think if a city has at least 4 surplus food when it grows, the highest production tile will get used regardless of how much food it has. So, mining a single hill or mountain tile can help a fair amount in an early Republic or Monarchy.
