MiG Alley is a combat flight simulatorgame developed by Rowan Software and published by Empire Interactive in 1999. It is a historical simulation which focuses on early jet fighter combat in the Korean War - specifically, the so-called MiG Alley in northwestern North Korea, for which the game is named. One of the interesting aspects of the game is the closeness in overall performance between the main combat fighter aircraft - the MiG-15 and the F-86 Sabre. Another is that the game was one of the earliest in the genre to incorporate a 'dynamic' campaign, in which the player's missions are influenced by in-game events rather than being presented in a predetermined order.
The source code was later released with permission from Empire Interactive under the "Empire Interactive License", minus the textures and landscape detailing.

Dave Whiteside: Because we are no longer doing flight sims [after Empire took us over at the end of 2001], and we would not be able to publish any patches that were required [no money was allocated to this], rather than let MiG die and all the code sit doing nothing it was considered a good idea, a swan song, if you like, for Rowan [after 13 years in the flight sim market].
