Did you notice all the other flight sims that have come out in the last 5 years? Oh, right, there aren't any. They all went out of business or switched to making something other than sims because a few tens of thousands of copies at $40 each doesn't pay for multiple years of development anymore. BoS isn't on Steam, either.
So since people aren't buying them in large numbers, you can either pay more for the new sim or you can keep flying your old one.
ROF now offers 9 planes for the ICE which runs about $20, and they regularly have sales where you can buy them at a big discount. For the $60 price of a Call of Duty you can get a lot of planes in ROF now.
But hey, flight simmers are cheap bastards and don't want to pay more than $40 every several years for sims, so is it any surprise that the industry all but collapsed?
Oh, and NO game works out of the box anymore. Not even the $60 annual CoD's that need patches and nickel-and-dime you for maps at $15 a pack.
So have fun living in 2000, but that era is as dead as the Bill Clinton administration and the twin towers of the World Trade Center. There's no going back.
