Agreed! Not sure how Nintendo would feel about forcing developers to create stamps for their games, but it would be neat if all games did have unlockable stamps that could be used anywhere in the Miiverse. They're certainly unique enough that it wouldn't feel like they were just copying Microsoft.I hope that Stamps becomes Nintendo's achievement-type system for Miiverse. They seem to put them in a lot of their games, even the casual games. It'd be cool if people were able to show them proudly without having to be in-game.
