I have played almost exclusively on terra maps for a while now, and I have to agree with other posters that it is heavily geared towards warfare. Playing Terra with Rome is almost cheating. That said, if you want to play the peaceful game and play a civ such as England or Portugal and actually make an effort to colonize the new world, it will be a much closer and possibly very fun game. The thing I like about Terra is that suddenly a lot of aspects in the game become more important, such as the age of sail and privateers, explorers, etc. I wish there was a way to generate a random terra map but make it so that the advanced resources (aluminum, oil, uranium) were all in the new world. Now THAT would be cool
