I've stopped trying to complete the Economic Legacy Path in the Exploration Age. Even if I rush Shipbuilding, the AI in the Distant Lands have settled most spots with treasure resources and the Treasure Fleets are so slow, I just kinda don't bother. I still try and settle 2 or 3 towns in the Distant Lands. I know I could be more aggressive, but I'm a peaceful player at heart and just want to chill. Getting Relics and Tile Yields are much, much easier to just chill and do. Treasure Fleets are so map dependant that I'm just now avoiding it. Same as Relics in Modern, much, much easier to just chill with Railroads and Flight, let them tick up instead of running around with Explorers. Only the Ancient Age is somewhat a rush to build the wonders, settle out, get the resources, earn money to make cities to house relics, and defend or attack.
