As alfredofroylan. There are no killer apps on launch. Most are all assed games, even the one from Nintendo (Pilotwings ressort and Steel Diver) are too short to justify 40$. This would be better with the next batch of games.
But we must first concentrate ourselves on the way to entertain people, for video games to live. Else, it's a world where sales representative will win, which has as effect to kill creativity. I want to say to the creators all around the world:"Courage, Dare!". Shigeru Miyamoto.
