What about doing something meaningful Nintendo, like striking a deal with third parties or something.
Who says they haven't tried? Before Wii U's launch Nintendo tried to strike deals with EA, Criteon and more. And technically Activision (SuperChargers) and this are third party deals.
Never used it. What's wrong?
Just a bit annoying, on normal android devices you have to have the app store file sent to your email, install that, then install the nintendo games, though you can not unistall the app store otherwise all the apps you installed through the app will no longer work. For normal apps, updates are usually pretty late, if not just unexistant. Just Google Play / Apple App store will reach more people and include better services for the user. And the app is clunky and odd to use.
Apparently Nintendo plans to announce a new 3DS title at E3, a Splatoon Action/Shooter Platformer 2.5D. Its described as a more fleshed out version of the cut arcade game, It will share a similar story to the main game on the Wii U. Unfortunately I couldn't get any more information then that.
