Why do some game manuals tell you a character's blood type along with the expected name, height and age? Watch for the significance of blood types in Japanese games and the blood types of the cast of Street Fighter, Resident Evil and Final Fantasy, mostly.

Seeing Blood Type in games like Super Street Fighter 2 was something I never really paid attention to. I never questioned why it was there. It just was. But know I know that there is an actual reason for it. Surprising and interesting.
