I'm not new to the game, just a bad player. I'm just now with BNW trying to put some effort into strategy and becoming better.... I'm trying to do a science victory with Indonesia and there's an obviously large benefit to the Civ if you can get 3 cities on 3 different continents. Each time I try this, by the time I've researched enough to be able to travel to other continents over the sea all the space on those continents are completely full and taken over by other AI Civs. Any strategy for winning this way? I have to be doing something wrong.
