I probably act the most like Edgeworth from Phoenix Wright; constantly striving for perfection (I've always been described as a perfectionist), a good public speaker, having a certain chivalrous personality that can be confused with arrogance (despite myself not having any self-esteem at all), digging for the truth in an argument, and being very sure of my own beliefs. Also, like him, I tend to separate myself from my friends for some reason or another. Though I think I don't really physically resemble anyone from any video games, again to pull a Phoenix Wright example, I would probably look like Detective Gumshoe if he was blond. I have no idea if that's a good or bad thing. Though in my younger, thinner days, if I had pointy ears I could have passed for Link.
EDIT: Also, for further support of my Edgeworth-ness, it has been suggested to me several times that I would make a really good lawyer.
