Riiverse

(Not to be confused with Rverse or the forum with the same name.)

Riiverse was a Miiverse clone created some time in late 2017 by users known as NintenBlox and Matrix. It was shut down, and as a result a user known as FunnyBone created a Miiverse replacement known as Wiiverse. Riiverse was brought back up under the domain rii.uiiverse.xyz, and was linked to on Uiiverse. It has since shut down again.
