This is as literal as the term "franchise killer" gets. Medal of Honor was a long-running war shooter series, having begun on the original PlayStation in 1999. It even got the Guinness World Record in 2008 for the best-selling first-person shooter franchise ever. So what happened?
Medal of Honor went the way of Call of Duty: Modern Warfare is what happened. And by that we mean the traditionally World War II-era franchise made the jump into modern times, but with exponentially less success than its rival series.
The 2010 Medal of Honor was not well received by anyone, but in a shocking twist the sequel, Medal of Honor: Warfighter, was much, much worse. We'd have thought that impossible, but they did it. They really did it. And with the series "out of rotation" at EA it could be quite a while before we see another Medal of Honor.
