An expansion of the dogfighting turn-based strategy hit, SteamBirds: Survival, focuses itself on October 15th, 1940. You must do all you can to hold off the Axis forces over the city of London so that civilians can evacuate. There will never be a victory parade since your defeat is assured, but you will want to last as long as possible all the same. Choose your plane, and Godspeed.
A turn-based aerial dogfighting game may sound bland in writing, but as SteamBirds conclusively proves, it's the whole nine yards of awesome. Working from a top-down perspective, you fight a series of increasingly difficult enemies with your small squadron of planes. Set your course, unleash a fancy ability if necessary, and try to maneuver yourself to a direct line-of-sight to your foe to set your guns blazing. And, you know, don't get shot down yourself.
