1. Kill Bill
I'm still amazed to this day, that Kill Bill has not matured in to a video game. I'm a member of many gaming forums, and this question has been brought up many a time. It has the perfect ingredients to become quite a popular selling video game. The number one reason I can think of, is the sword. The sword alone can amass all methods of madness. You could play this game, just reduce stress levels. Imagine taking out thirty to forty bad guys with your samurai sword, in a seemingly gruesome yet pleasurable fashion. Admit it, it sounds good doesn't it? But beyond senseless slicing and dicing of your enemies, Kill Bill would actually have long term play-ability due to it's impressive storyline and fantastically developed enemies, which as we all know, gamers absolutely love a good bad guy to prove themselves against.
