toys for kids

So I get my son this WII U and I know he wants it because every time the commercial comes on he is all over it but what I don't get is the prices for the games they are almost the same as the console why is that then they have all the different attachments and gadgets also how come they can't sell it like they did with ATARI or INTELEVISION or even the first NINTENDO any thoughts or suggestions or comments please
