Mid-tier nerd. I know there are people out there who actually run around training to becomes Jedis. Folks gotta do, I suppose.
Prior to the movie, I went out and bought the toys when they arrived at Toys R' Us, and before that I'd been buying the re-issued toys. I remember having to explain to my pre-Jamie girlfriend that, yes, I WAS going to buy an X-Wing fighter, right in front of her.
I was never much of an expanded universe guy. I guess I knew from a young age that anything not in the movies-proper didn't "count", and that the books at B. Dalton and Waldenbooks were a cash grab as much as the Marvel comics with the green rabbit character, but nothing the movies wouldn't run over in a second as it seemed laughable that George Lucas read any of that material.
When Episode I came out, Jamie and I stood in line - she, fresh out of the hospital, and wearing my Darth Vader helmet (it wasn't a size 7 7/8ths helmet, so it never fit me) and carrying my Vader light saber (I carried my green Luke light saber).
We were in one of three or four midnight showing screens at the Gateway theater in North Austin, and there was a huge party atmosphere. Light saber duels on the stairs and people cheering hard against the late hour.
The credits came up, we cheered. I remember thinking "oh, this isn't entirely what I expected", and just let it wash over me.
