7. Chuck Yeager's Air Combat
PC, 1991
This game will not feature on 99.9% (if not a higher percentage) of Top 100 Game lists and I accept that. However, for me, this game dictated my younger gaming years and therefore is dominant in the reason I love video games. It also helped me learn a fair bit about the history of air combat and introduced me to Chuck Yeager himself.
This game is both basic and yet very in depth for it's time. It covered most of the more general things you'll get in Air Combat games released these days and allowed you to participate in dogfights from World War II, the Korean War and the Vietnam War. In all instances, you could participate from either side, so that meant you could pick up a MiG just as easily as a McDonnell Douglas (my fave plane was always the Phantom). You could also create your own battles, meaning a score of Spitfires could happily make attempts to shoot down a supersonic jet. In these custom cases I'll openly admit that I would use the cheat options and just get the satisfaction of taking down far more foes than I reasonably should.
Anyway, I loved this game like crazy and it's possible that I've played it more than any other given that I would play it regularly for years, possibly as much as all the other games I had combined, before consoles such as the PSX took hold of me.
