From the PlanetPlaystation.com feature list:
"This is one of those topics that will be debated til the end of time, is the Xbox 360 or Playstation 3 better and which has the better video game lineup. Well both have third-party games a plenty, and that's counting the huge sellers like Modern Warfare 3, Madden Football, Skyrim, Dead Space, and so on. What really gets people going is which system has the better exclusives, and that's what I'm going to look at today in our feature article: The Top 10 Best Playstation 3 Exclusives. Obviously this is just one person's opinion and it doesn't count what hasn't been released yet but for now just make sure you have at least played each and every game on this list, because they are all fantastic reasons to own a PS3."
