I think that`s a good idea, but Nintendo should go beyond that and do something special.
Instead of giving people gifts for the achievements, why not create a free game where you can, not just battle character vs character, but console vs console.
What i mean is that in a game you get the chance to evolve your character, but the problem is that it`s just ingame. What if you can take all the purchases you make (1st party and 3rd party - by genre too), how much you advance in games, how much you use the consoles apps, what programs you adhere too, and make it all count to develop your console character and then create a fictional character in said free game and fight other console/players worldwide?
People seem to love achievements and online competitive play. That could be a good way to make Wii U stand out.
Also, if people buy Nintendo consoles for Wii U games, why not ease that process and allow for people who download a 1st party exclusive to sell the digital license after owning for, like,6 months. If you keep it for a longer time, Nintendo will reward you - like Banks and interests.
More people would be willing to buy a Wii U (more would be xposed to 3rd party games too) seeing as they can buy the digital version and then resell it if they wanted to sell it to buy something else. Like a exclusive 2nd hand gaming store.
