In the old days, you launched a console with your Halo or your Soul Calibur or a groundbreaking Super Mario. Since the PS2 (original Xbox the exception), nobody seems to launch with an exclusive big gun. They just seem to get the product on shelves and worry about the "killer app" later.

The Wii launched with one of the most potent killer apps in gaming history in Wii Sports.
