Topic is simple.

I would have pushed for  Pokemon Snap, Metroid Prime, and possibly a Mario Baseball at release, because I could see how you could easily work the gamepad functionality into those games to make it more than a useless addition.

The thought of using the gamepad as a camera for in game actions is hopefully going to be covered by Fatal Frame, but should have been there from the start seeing as the gamepad is supposed to be a major selling point. I'm not sure Fatal Frame will do to well though. The Wii U already had a great survival horror game that made good use of the gamepad and and creative multiplayer to boot, and it bombed, possibly because the Wii U audience isn't the type that's appealed to by a new Zombie/Survival Horror IP.

So if you had to, what would you do to try and incorporate the gamepad into gameplay experience?

Kind of hard to say with theoretical games. But yes Pokemon Snap or Fatal Frame on release would really help the use of the gamepad. Or even an RTS game.

With regards to existing games I would have released Mario 3D World close to launch to show Nintendo means business.

Nintendogs is obvious. I would have had a 3rd person open world survival horror Metroid, a Pokemon console RPG, and an open world Mario game come out within the first year.

I would like to see a real 3D kirby game that would make some sort of good use of the gamepad

Unless the 3rd party make their slate of games a priority or even just availability on Nintendo console, all the rest of what Nintendo does or doesn't do for home console is irrelevant.

Honestly, if the 3rd party were on board, Nintendo did everything right, and if not, then everything wrong. So what discourages the 3rd party on Nintendo system?

Lack of meaningful online features. Weaker hardware than other next-gen. Different architecture than the x86 architecture adopted by the others. Released poorly with barely working OS (slow and unstable that took more than year post-launch to patch into acceptable norms). Poor sales adoption by any core gamers or casual gamers.

Glad you could give us your insight on the topic. Keen reading comprehension.

Also, wtf at Gamestop being sold out of Wonderful 101 and it passing Watch Dogs on Amazon Best sellers?
