If Nintendo's website or services fail, malfunction, or cause problems, Nintendo is not legally responsible because they have disclaimed all warranties.
Nintendo's Terms of Use significantly shape users' legal rights by requiring binding arbitration for disputes and waiving the right to participate in class action lawsuits. The terms also grant Nintendo a broad, perpetual, royalty-free license to use any content users submit through their platforms. You can opt out of the arbitration agreement by sending written notice to Nintendo of America within 30 days of first accepting the terms.
