Forgive me if this has been posted before (I did a search for this, but found no mention of it)
In a January 1, 2010 podcast from 1Up.com (4 Guys 1 Up), Sega of America studio director Constantine Hantzopoulos mentioned that he and the development team Monolith were considering a new Streets of Rage game using the Condemned engine for their next project (at the time).
He stated that "Escape From New York" was the main inspiration for an open world (sandbox?) style game.
I wonder how that would've turned out. I'm assuming it would've been a 3rd person style brawler. Hmm...
