If you want to get involved with playing flight simulator games, or reading books, then you must set aside a large slice of time to do so. As society, as a whole, transitions to the era of attention deficit, producers of long form content will be-- or have been-- forced to economize on the production of their goods.
In software that means less new titles in the market or more hobby projects, like the Crisis mod.
Also, flight sims do not lend themselves to MMO. Since you have an extreme gradient of players; at one end, players that want the most realistic simulation (one that you follow the rules), and the other where you see if you can get the 747 to do a loop-de-loop.
