Sailor Moon? Ah~~ natsukashii~~ ^__^;
Heh, like most other people here, Sailor Moon (dubbed) was my first anime. Although I didn't grow up on it, as I discovered it in high school. (I "grew up" on Disney movies, Rainbow Brite, My Little Pony, and all those wonderful 80s cartoons. XD) I've seen the whole thing dubbed and half subbed, all of the Seramyu minus Marina's stage (other than Ryuusei), and half of the live action. The live-action was... interesting, to say the least. It was horridly cheesy, but was nice in that it had a fresh new take on the storyline, and I liked some of the character development (Mars and Jupiter's actresses I especially liked). But I'm not even going to comment on Sailor Luna.
Then I pretty much became obsessed with Sailor Stars and ignored everything else, and now I've moved past it. I wonder now if I could even go back and watch it, as so many of those 200 episodes were horribly filler-ish, although in an endearing way I suppose... which makes it a classic, I guess. ^^;; Though I think I could watch Stars anytime.
Merchandise? I have so much completely random stuff. I have almost-complete sets of the full-size and 6-inch dolls sold in the US, a Mars plushie, a Seramyu DVD, a pencilboard, a pile of keychains (including Luna who's on my key, and my precious Starlights on my shelf. ^^; ), the Mixx Stars manga, two artbooks, some random stationary, Seramyu trading cards, a Seramyu program flyer, and of course my beloved Starlights doujinshi which I spent loads of money collecting. XD
I always loved Haruka because she was just kick-***. And Mars, for her fire and mystery. I used to love Mercury, but grew to hate her because she reminded me of myself because she was annoying.
