Think of it as an investment in time. Bijan has sunk 100’s of hours into perfecting these season add ons, and continues to sink many 100’s more.

As these addons affect the whole world, the whole of the time you’ll have hundreds, if not thousands of hours of flying enhanced, not just today, but even two or three years from now.
Finally, the $60 you spent on the stock game is because its auto generated, the premium and deluxe versions run to $120 because of the personal care and man hours to hand craft the extra planes and airports. Stuff that requires a human hand costs more.
