Remember the opening scene of Babylon 5 (not the pilot, the actual series), where Narn fleet attacks a Centauri space station in Ragesh III I was sold the moment I saw that, as it made an immediate connection to my favourite PC game intro - Master of Orion 2.
Did you assemble and paint WW2 military aircraft as a kid? I did, although I really didn't like much the glues and paints used in them, the ones I'm using currently in modelling and with miniatures are way easier to handle, an healthier too I guess. I also read Commando -comics and was generally fascinated about technology of The Great War. If you are also Plasticrack addict(tm), you'll be easily tempted to these.
