It appears that Nintendo is allowing gamers to publish reviews of Switch games on its website. This means that gamers who surf on over to the Nintendo website to browse for games will be able to see reviews and ratings of the game left by other players. At the moment the listing for reviews isn’t as intuitive as other systems, although this is largely due to the fact that Nintendo’s website also plays home to a bunch of other systems like the Wii U, 3DS, and more.
Hopefully this is something that Nintendo will improve over time, but for now at least a ratings and review system has been put into place. However note that gamers can only leave reviews on games that they have played for at least a minimum of 2 hours, which means that this should reduce the chance of fake reviews or review bombings. Users will also need to log into their Nintendo accounts to leave a review, which also helps verify who they are.
