Regarding Polynesia... I've always liked this civ, its just fun to play. But I never did that well with them. I always felt like I was losing badly, so I would quit early. Finally I decided to stick it out. I still didn't think I was doing well, but at some point after airports I looked at my tourism, and for a second I honestly thought something was wrong. I was making something like 900 tourism a turn. Usually at the end game there is some pressure, some competition, but I won that game before anyone had even built the Apollo program.
