1. Campaign is unwinnable as in the last scenario, you need 10 trading partners & the 10th, i.e. "Persia" is still only a discovered city, not interacting at the end of 8th year in that episode. Maybe some time-dependent event didn't kick in as I finished later episode pretty fast.
2. Title here on description & the actual adv. title don't match.
3. There is no story & language is also a bit difficult to follow :( .
