So uh, there was this map mod that, I remember, but I have no pictures of, that consisted of an island with some skyscrapers and there was also a blimp with "simpleplanes" written on it. It is not New Portum, tho the concept is sort of similar?
That's pretty much all of what I remember, if you guys know what happened to it or if it's still available, I'd be very thankful
