Agreed, I'd be on it nonstop. It would be difficult to port it over to the consoles, but it would be great if they did. It would probably be best to charge $30 for the game, get rid of the monthly Live fee (somewhat included in the higher purchase price), but could still charge the per aircraft/region price or do the annual to unlock everything.
The way it is now is fine for a mobile app, but if you go over to console then pricing would have to change. In my experience a lot of console people aren't big on monthly subscriptions.
