I didn't start playing Call of Duty until Modern Warfare came out. The only reason I even purchased it was so I could play the multiplayer because so many people told me how cool it was. After purchasing it I realized that the campaign mode was also off the hook! When World at War came out it was just the right thing to do to purchase it as well. As for it though the only reason I still play it online is for the zombies. Ive never really been a fan of the WW2 era in video games. I like my gameplay modern. I'm not to big on future settings either.
