I took a look at the rest of my map, and yes its pretty much mines and snow. Everything else has gold.You should be positive in gold once the golden age begins, right?
I wonder if gold has been added to many tiles which means means its easy to double it via golden age.
I can find only 4 tiles that don't give gold in the above image
- Empty snow
- Marble (will give gold if stoneworks built)
- Empty tundra (which qualifies for a trading post)
- Some mines (with iron or any luxury they give gold, or with industry)
