whereagles said:Get rid of it. It is unrealistic. Make it free movement for the first 5 or 10 tiles, but no more railroad move that turn.
Keep the free movement for the railroad! Civ will be extremely boring if we have to take forever to move our workers from one end of the continent to the other to clean up pollution or whatever.
The reason why StarTrek is so popular is because they have the technology to travel at warp speed! If we take away warp speed, StarTrek will be boring like hell. It's the same reason why we have Town Portal or Dimenional Gate spell/technology in D&D and sci-fi games.
