I'm playing an Austrian game on a Huge Earth Map, on immortal. Started in western France, expanded towards Europe, married Hong Kong (in Germany) because it was too close, Jakarta (south Turkey) because it had high population and was on an amazing spot, Monaco (South Egypt) because I got a load of money from an American "The Backstabber" peace treaty, Antwerp (north Caspian sea) because it had many units and was close to Washington and Almaty (Benin), because it had coal.
The ability is quite good. I went liberty and, even though my cities' population are low, I'm cranking a lot of GPT. In a few turns I'll marry Singapore, 18 pop, modern era, so my SPT will greatly increase. I could go culturally, but I'll try for the spaceship. The Coffee House is great for Scientists as well. My main problem is Unhappiness... yuck... But apart from that, Austria is really great.
