Just won my 6th game at Regent ... Spaceship by the skin of my teeth. Standard map, Sumerians, ended up on a relatively small continent with scarce resources, by the time I was able to travel even by Galley, most of the land was already taken up, and the one town I put elsewhere flipped to the Iroquois very quickly. Nevertheless, managed to trade my way up on resources & tech, build the UN (also very close - would have lost if I hadn't gotten it), and only got into one war that was never fought (Persians DoW on me, but we ignored each other and just made peace eventually). Not one of my top ten games, but the toughest one yet due to being unable to expand very far.
