How could Rockstar top its Undead Nightmare zombie-infested downloadable content for Red Dead Redemption for the Sony PlayStation 3 and Microsoft Xbox 360?  Just add dinosaurs!  As seen on Reddit, this hypothetical addition to the plains of New Austin and points beyond would give protagonist John Martson a lot more to worry about than just cougars and coyotes.  I would definitely buy this DLC if it actually existed.
