Blood types in the Street Fighter series

[Kakariko Kid]

In character profiles in the Street Fighter series, blood types are listed along with statistics such as height and weight.
Ketsueki-gata, or ABO blood types, are supposedly predictive of personality traits, temperament and compatability with others, made popular in the 1970s by author Masahiro Nomi.

Other Japanese developers use this, also. Albert Wesker, of the Resident Evil series, has type A blood.

Kakariko, with all due respect, I don't think this is trivia worthy. The Japanese think blood type plays a large role in defining a person's general personality. It's not all that different from how we (in the general sense) think that the day you were born plays a large role in defining a person's general personality. Think of it as the equivalent of a horoscope, but with blood types instead of birthdays. Either way, it's superstitious nonsense, though.

Heck, if you want an specific example, let me tell you that this type of info is also mentioned in anime/manga such as JoJo's Bizarre Adventure and HunterxHunter.

There, just leaving my 5 cents.

[SERIOUSLY THOUGH*]

I disagree.
One simple question to determine eligibility :
Is this an interesting tidbit of information about a game ? Yes.
