The developers clearly did not try to promote the series anywhere except for graphics.
Streets of rage 4 is a game in the spirit of the good old parts: a poor plot, strange pretentious scenes and moderately complex and interesting gameplay that can be played in co-op.
The developers adapted the classic visually very well, they couldn’t have come up with a better idea, but the lore of the game... Well, really, you could have tried?
