AUDULTS ARE NOT THE ONLY PEOPLE IN THIS WORLD FOR GODS SAKE. They made it to enjoy children and adults. There just doing the kid games first!
Why did you buy a wii? If you want some gory murdering game get a 360. Should'nt you have known that the wii was to impress children and adults?
And think about it. They had to choose what games to start with. I guess they started with the kid games first.
PS: I am no fanboy. I enjoy nintendos product. I have to say that the 360 is an awsome console though.
