I have to preface this article with this statement -- once upon a time, I had absolutely no confidence in the eShop. Initially, I saw a marketplace where Nintendo was slowly drip-feeding us 20 year old games once a month. I saw how WiiWare had been weak out of the gate, and shriveled into something you could barely call "The dirty flea market of online stores" -- at this point people should call it "3DS Download Week" instead of "Nintendo Download Week".
As of now, not including the 20 ambassador games, I have around 30 eShop squares housed on my 3DS -- suddenly, I feel a lot more confident about the Wii U's digital plans. Feel free to check out the below list, and tell us what you're thinking of picking up.
