"Long before there was Battlefield 3, there was Call of Duty, and before that, there was Quake and Doom. All those games can trace their lineage back even further, to Wolfenstein 3D, iD&amp;#39;s awesomely innovative Nazi-hunting FPS adventure. Today marks a milestone for the classic franchise: B.J. Blazkowicz has been blasting SS guards and chaingun-wielding robo-Hitlers for a whopping 20 years."^^<http://www.w3.org/2001/XMLSchema#string>
