Before there was Call of Duty or Medal of Honor there was Castle Wolfenstein. The 1981 game that I spent hours playing on the Commodore 64 bares little resemblance to any of today's first person shooters but it did pave the way for the 1992 hit Wolfenstein 3-D. This game changed my life. Probably not for the better, since I spent most of that summer sitting in front of a computer killing Nazi’s and eating microwave corn dogs.
