Little help required here.

To celebrate my 2000 hours playing this game (see above), I’m looking for a challenge different from my usual builds.
I thought of throwing up a poll with four random airports from the list in the Airports json file (all 2957 of them) and asking for votes, then tailoring my play to whatever wins - any other ideas?
I know (by experience) that it’s no easy task. But other people have done it before, so its nothing novel.
