Airports are not a new idea. They already exist,but only in the two maps:one of them depicts Skåne (Sweden)and other one Austria. The idea of connection of cities with airports is just a wonderful idea,but so far only present in two maps(expect if I still ha e not unlocked some).
Please try to make a map with airports!
Have a good day!

Hmm, there are other maps with the same concept, just not "airports" more like teleports (unintended pun) . Not sure if there are other world/country based maps like that thru. Are you interested in that. (I guess the connections are not everything to everything, bu stuff like two teleports to each other)

There exists an interesting ,,Hopscotch" map,where territories do not connect their neighbours,but territories that their neighbours touch. However,it is very small and not so good rated.
Please send me a link to some of the maps you have mentioned!
Have a good day!
