The dawn of Nintendo's success comes from it's kid friendly games and family oriented experience. Nintendo wants to market to the traditional American family game night. Families have always strived to create activities to bring them together, this is what Nintendo thrives on. If a family wishes to come together to have fun and enjoy each others company over thrilling games, than they can accomplish it with a Nintendo game console.
Nintendo made this clear to other video game industries with their introduction of the Nintendo Wii game system. Utilizing it's motion sensitive controllers Nintendo was able to rise to the top of the market share over Microsoft.

Nintendo includes not just the gamer target market but families too; mom, dad, sister, they can all partake in the fun on easy to learn games. Microsoft's console, the Xbox 360, catered to the original gamer used to first person shooters and other thrill seeking installments.
