| because it's one of the few franchises that has been able to continually reinvent itself over the years. There are literally hundreds of such franchises. Just look at this summer's blockbuster lists. And in video games, there are plenty of examples of franchises that have lasted 15+ years (CoD, Madden, etc). It's just very difficult to know if a franchise will have staying power. Many sequels are tried, only some succeed.
