I first saw all the movies when I was 12 I think. I don't remember which one first, but they might be looked at in the right order.
Very much more importantly and imprinting for me (and that's kinda connection to this game above) was my first computing and PC games experience, which was with this first colored Star Wars Game, where you had to yet through the canyons and the death star with your X-wing!

That was sooo cool, I really loved it!! I were really addicted to it! ^^
Afterwards, I was so fascinated from the StarWars games from Lucas Arts, that I bought myself the whole JediKnight series and played them all through.
