I think space force was my 2nd favourite force. Which surprises me now I think back - it should have been Z-force being logical about it seeing as they where more "army-like". I was never very keen on starwars either so why I decided space force was cool is beyond me... I suppose space force was introduced by palitoy to appeal to kids who like starwars and such like, I don't know I'm just guessing...
But I liked all the bits of equipment the space force figures had - the laser guns, the uzis, skyraider's cap, and the helmet on the pilot with the flip down visor. I even thought the flying brick (the cosmic cruiser!) was ace... I think I can remember using skyraider as eagle in civies whilst recreating the opening scenes of 'The Baron's Revenge'.
I can't remember if Duke and co ever went into space?
And as for Q- Force the only figure I had was the dep sea defender - I don't think I ever really liked Q-Force...
