Got 'Fly!' for Christmas 1999. Very disappointed with it- so I downloaded the 10MB patch. Which didn't really improve things.
Graphics are no better than FS98, aircraft are difficult to 'learn' (i.e. keyboard shortcuts for things like 'flaps up one stage' are not as a FS user is used to- although they can be reassigned, after a fashion) and the flight planning screen is a farcical distraction.
You can, if you want, download better terrain. 50MB, from
