Streets of Rage Remake was in the Works at Crackdown 2 Developer
So here's an odd story. Ruffian Games, creators of Crackdown 2, were working with SEGA on remaking the classic Streets of Rage franchise for modern day consoles. A two minute video was leaked to the internet showcasing the game's graphics, environments, and even some gameplay. It's easy to see some of the Crackdown influence in the fighting engine, but it definitely looks like this could have worked.
