Nintendo's latest Wii Channel, Check Mii Out, greatly facilitates the sharing of personalized Mii avatars. However, GameCritics opines that the channel was way too late for the party to allow creative talent to make a geniune foothold. Since the launch of the Wii, the relative inconvenience in sharing Miis before Check Mii Out's debut meant it was simply easier for users to post tutorials detailing the creation process of their Miis.

These tutorials themselves are meant to be useful guides for personal use, but GameCritics laments the number of contributors on Check Mii Out who have used them to basically copy other Miis to post as their own. We can imagine that not all such contributions are truly malicious in intent; if a user has a Mii he/she likes regardless of how they made it, they may not feel it is wrong to post it for the purpose of sharing. On the other hand, it is also not unreasonable for the original creators to ask for proper credit. Unfortunately, as with other types of game contributions here or elsewhere, this is not always easy to establish.
