Sims Airport & Sims passport & Create Real countries for Vacation

I happen to just think of another idea to bring to the world that I hope to see Sims develop in the next packs. I would love to see the Sims franchise create an airport for Sims to travel and to experience the traveling by air to other countries option and applying for a Sims passport in order to travel like we do in the United States. Also see the Sims create real countries for sims to travel to and experience culture while on vacation.
