Why did you choose this character 2B your main
I've mained Sieg since SB. I remember the first time I ever played the game, soon after GameWorks opened in Seattle. I found the SB machine and just got hooked on it. I tried most of the cast, but kept bouncing between Siegfried and Rock. An employee noticed that I was glued to the machine for 30 minutes or so, but no-one else was playing it. Don't remember his name, but he was a cool guy. We ended up playing on his employee card for an hour (maybe two) and I settled on Sieg. (I also played through House of the Dead twice with this really cute girl who worked there, that was fun.)
When SC1 came out it was huge with my friends. I had a couple different groups I'd play with, and everyone mained somebody different. Each of us escalated our game to try to get ahead of everyone else, and I totally fell in love with Sieg's stance roulette. This was the high-point of SC in my life, and I still associate a bunch of people with the chars they played back in the day.
Then SC2 came out, and we all hated it. We stuck with SC1. Partially it was specific changes to the system that turned us off, but mostly it was just the feel of the game. I know people love it to death, and only some people understand what I mean when I say this, but SC2 just felt... mushy. It was like going from a crisp digital game to a fuzzy analog game (I don't mean the graphics, btw, more like the feel of the controls, buffering, step, hitboxes, etc.) It worked out somewhat for me, though, because I just can't play evil characters. Mental block, make fun of me if you will, but when I did play Nighty in SC2 (3P outfit, always) it bugged the crap out of me to hear Siegfried say things like "I'll devour your soul!" (not like we ever used English voices, but whatever, "tamashii yo!" sounded just as pathetic.)
I wasn't sure what to expect from 3, but when it came out I fell in love with it. Yeah, the game had its faults, but it *felt* like SC1 again, it had beautiful art and music, and best of all Sieg's stance game was more fun than ever. And I know this is silly, but it made me happy that all the Nightmare fans weren't playing my character anymore, and that Siggy was back to his SC1 heroic self.
I guess this turned into another long post. For me, really, I play Siegfried because I think his playstyle's fun, and because I'm just so used to playing as him. There is a bit of brand loyalty there. But when I think about any kind of sentimental attachment to the character, it's not just who I play but more the notion that we all played someone specific. Having that group was fun, and while a couple of my old buddies still play, I've been having a hard time to get something going regularly. We used to do near-weekly Soul Calibur Fridays, and we haven't done that in a while. Who knows, maybe when I meet the other Seattle players I'll make those person-to-character attachments again, but I think it was just one of those things you get once when you're young and don't experience the same way again.
