Go to nintendo.com. Click on the "Corporate" option at the bottom of the screen. Then click on "Company FAQs" and select the question, "How can I submit my game idea?" Here you are given the information on Nintendo's submission policy, and you're also given the reason for why Nintendo is unable to directly take your submitted ideas.
If you want to make your video game ideas reality, you will need to be dedicated to pursuing a career as a video game developer. Nintendo suggests that it is helpful to take classes in C++ and graphic design. Several institutes offer computer engineering programs, and Nintendo also suggests that the DigiPen Institute of Technology has a great program for aspiring game developers (see Resources).
If you already have the credentials and skills as an established video game developer, then contact a Nintendo representative. For help on getting one of your video games licensed, you can go to the link provided at the end of the submission policy, where a hyperlink is presented for email contact (also see Resources).
Another option for sharing your ideas with Nintendo would be to work for Nintendo of America. Once again, from the main page of the official Nintendo website, click on the "Corporate" option at the bottom of the page. Now, click on the "Jobs" option at the top of the page. You will be brought to the "Career Opportunities" page, where you can search through recent postings of job opportunities at Nintendo. Create an account to apply for a job.
