The warriors is fucking great. The beginning hour or 2 has nothing to do with the film, you're just a gang in coney island, beating up other dudes, robbing people, participating in riots, then you get into the story. Then there are stories of how each member came to become a Warrior.
As far as rockstar "bonus" games go, The Warriors is the absolute fucking best.
Don't take it from me, take it from this delightful zoomer.
ETA: As I'm typing this I'm downloading The Warriors on my PS5, I remember on the PS4 I had some buggy issues with it the color was fucked up like nothing was the right color, apparently they could be fixed but I didn't get around to it.
It was my favorite fucking game when I was 12. Let's see how much I love it in my 30s.
