This is why I think that both Shotokan and Kyokushin are very popular, not just in real life but in games too. Ryu from Street Fighter has a style that is supposedly based on Shotokan, Jin Kazama as you know is Kyokushin, there's a character from Virtua Fighter 5 Final Showdown called Jean Kujo who uses a mix of Kyokushin, Ashihara and Enshin. Hitomi from Dead of Alive has a father who taught her Kyokushin. It seems that they're either Shotokan or Kyokushin but yet you never see a character who uses Wado-Ryu, Isshin-ryu etc.
