Streets of Rage 4 I could have had Joe Musashi, protagonist of the saga Shinobi, as a playable character. However, the SEGA internal bureaucracy and other problems related to the Japanese company prevented it, as he explains Jordi Asensio, one of the developers at Guard Crush Games.
In an interview with the French Twitch channel Gwak in which the developers of Guard Crush Games: Asensio, the programmer Cyrille Lagarigue and the composer Olivier Deriviere participated, explained that the SEGA's Japanese division rejected the idea of adding Joe Musashi
The reason, they argued, is that SEGA is a huge company made up of several smaller entities, and they only had contact with a small division of SEGA Japan. The inclusion of Joe Musashi depended on what SEGA section has character permissions, "and many other things", according to the translation of DualShockers.
Although the protagonist of Shinobi was not included in the game, Streets of Rage 4 has multiple tributes to the games of the Japanese company, and a lot of elements from the previous Streets of Rage of Mega Drive that are implemented in the gameplay of the new game.
