My vision for it was that it should be a world simulator. You get it for free, and walk climb anywhere in the world for free.
And then you have the Flight sim addon, and the train addon, and the farmer jones addon, etc. Despite what you would call it that would be great.
Wake up get in a taxi to the airport get in you plane and fly, or goto the train terminal and train? lol, or get into you boat simulator and boat etc etc etc, and all those other modules would interact with the main world simulator. Of course if you wanted to drive a boat you’d have to buy that mod for the sim. But hey if you get tired of flying all the time why not capt a big ship across the ocean or a little one across the world. ETC.
