No naval carpet of doom problems seen in my game. Their building navies but are using them (against each other) Oh, I had an immediate use for Radio. I'm after cultural victory in mine and faith bought a GE the turn before Oxford completed and rushed Effiel Tower with it in addition to being the first in the world to choose an ideology. I actually did have coal but I can always reach Radio faster than build 3 factories. That actually is the last critical world wonder to my cultural victory strategy, Broadway or Sidney would be nice but not needed.
