For the time, it was a good game. I remember spending countless hours with the manual trying to understand everything, and numerous afternoons learning how to land. As a concept, the game is quite good: 8 dynamic campaigns of increasing difficulty (but without the option to choose the difficulty).
That's why I decided to play it all the way through. The game, in terms of AI, at least the MS-DOS version, leaves a bit to be desired, but it's quite fun to play for a while. You can see the complete gameplay on YouTube if you search for OnlyEarlyAccessGames and look at the playlists.
