Though the differences between Nintendo's Miis and both Xbox Avatars and PS3 Home are numerous, perhaps the most conspicuous separator is the fact that while Sony and Microsoft have looked to monetise their services, Nintendo has not.
And it doesn't look as if Nintendo has plans to change that any time soon.
We don't think the idea [of charging for Mii items] creates value for the consumer,” Nintendo's American president Reggie Fils-Aime told Forbes.
Consumers love to make Mii's and that has been core to the Wii experience. We don't believe selling clothes or hats is something that the consumers will find valuable. And candidly, if you really challenge the competitors who are playing in this space, I think they would be hard-pressed to show any true value from a consumer standpoint.
What we think is important is providing real experiences. So the content drives that.”
