Yeah even the self proclaimed "hardcore" gamers I know never even heard this game.
Those of us game enthusiasts who would be in the market for a "core" game on the Wii also have to wipe the stigma of "On Rails" shooter as well as "Spin Off" of a second rate(though highly rate talking sales wise here) "Third Person Shooter".
Finally the game just does not look that great I would say uninspired even but I shall rent it one day when I get around to it.
