The current tram system takes up a lot of surface space, that would be more well used for other things.
Also metros are cool
How?
Simple build a couple of metro stations and connect them with tunnels. We can also move some water elevators to the metro stations which will make the surface (especially blair mountain str) look much nicer.
Good idea, but currently the city is so tiny that it'd take more time getting into the metro and going places than just sprinting or flying. Although if you could figure out how to make stations work that would definitely be great.
