The Amino Community is a much more approachable and inviting community than the Discord community often times, as instead of being sectioned off into servers and such, Amino serves as one huge hub for many players to find all members posts and content in one place, all organized based on what type of content you are trying to find. And while competition is best taken to the Discord community, there are a few Amino based clans and tournaments for members to take part in, often with a lot lower stakes than competition in the Discord community. whether you are a budding fan-artist, a new player, or just someone looking for some friends to enjoy Splatoon with, Amino serves as a great entry point into the Splatoon online community.
