Nintendo recently added a User Review section for games such as Splatoon 2, but the feature was removed for evaluation soon afterwards. [Thanks, Polygon!]
There is no estimated date currently on when the review system might come online again, but Nintendo of America has commented that the user review system was just a trial that received positive responses:
“Nintendo.com recently offered a trial customer review feature to let users share feedback about Nintendo Switch games on our website. The response has been positive, and Nintendo appreciates the time and effort that reviewers put into their thoughtful commentary on the games. Nintendo has removed this feature as we evaluate the future of the ratings functionality on Nintendo.com. We have no estimate on when an update will be provided on the status of this initiative, but we appreciate the enthusiasm shown for the trial.”
