In most communities I find that involve characters being pitted directly against each other, there's generally one people will choose more often than any other, and which character that is from person to person tends to get brought up a lot. You could say who you main says a lot about your playstyle and the mindset you have when it comes to games - or, if you prefer, you could say that's a big buncha' malarkey and people should just play who they want. But then some say your choice of character could say THAT about you. It can be convoluted sometimes :P

Anyway, since the Dreamcast has so many fighting games, I figure, why not discuss who we main in all those and why? Doesn't have to be fighting games specifically, but those are usually what this whole thing is usually associated with.
