Erik, I think you're writing on the same page I am and not realizing it.
I do believe I said marketing, design, appeal, etc...are what has attributed to the success. Even a Blue Ocean strategy alone won't work if you don't meld these aspects into it as well. The new market must be tapped correctly which is why I called it the casual market because so far no console had tapped that market correctly. The casual market was still blue until Nintendo came along.
I'm really not sure how you can say Metroid Prime 3 was designed to appeal a greater audience than ever before given that it's still targeted for the fans/core audience. While it may have more appeal to former non-gamers/disenfranchise gamers simply because of the consoles they are on, the game isn't as approachable as say Nintendogs or Wii Sports.
