make a mall under the ocean or in space,someplace interesting like maybe
under the map or make a tram to 2 points and there will be transport. :)
or make a mall in a teleporter world globe with a waterfall and trees.
and a sun kind of like a Dyson sphere effect.:)
or make am elevator to the clouds or space and have a mall there
with no fall damage.
then people can jump from orbit or have fun not crashing toast is
they jump down.
or make 2 Dyson spheres and add a tram and call it cloud city.
no lack of imagination here that's for sure.
