To give my brief sum up of what Nintendo is: It is one of the major early gaming companies alongside Sony and another company I'm too tired to remember the name of. Nowadays Nintendo mainly makes games aimed at child audiences, though occasionally they have a rather mature game come out.
Too bad every guy I ever met never cared about video games. And if they did care, they only cared about the newer shooter games, with the rare occasion of a pokenoob.
