Movie: The Blues Brothers
Game: Saints Row 2
Book: Guns, Germs Steel (haven't finished it yet tho)
I'm imagining a Chicago street gang, who dress and act like the Blues Brothers (Suits, ties, hats, shades, Rythm & Blues musicians), and the history of why they, and no other gang ended up controlling the world.
(Interesting fact: I actually completely changed the style of my SR 2 char and my var to fit with the Blues Brothers theme, since I had just watched the movie and hadn't played the game for a while. So I was already combining the two.)
