With so many new areas being opened in some of the regions, I was wondering if there was a plan for additional subway lines through the regions. I don't see the two red/blue lines being able to handle many more stations (except for maybe to the islands). So I was wondering if regional subways were coming...a subway line for Mazza'la and a separate one for Grumbla where they also use the current subways in place as transfer stations to the red/blue lines to move between the larger land masses.
