Choosing actions/items in JRPGs/WRPGs would be so much easier with a touch interface. I also wanna see a good art game for WiiU, 3DS screen is too small. Maybe a cool ghost game where you can only see what the tablet is pointing at? Would be so creepy (anyone play Silent Hill Wii?)

The most obvious but certainly most useful is having the map and the inventory display on the controller, after playing Darksiders 2 I imagine how useful it will be to have all your weapons and armors constantly display on your hands without to pause the game every time

I read the title as "good uses for the Wii controller" and thought of something that's probably unsuitable for the forums xD

As for the WiiU controller, it'll be great for inventory management/maps etc- but I'm looking forward to the panoramic view too

Rear view mirror in Mario Kart.
Sword swinging action in Zelda (kinda like Infinity Blade by Epic on iOS)
Detective mode in various games (like seeing ghosts)
Inventory
Maps
You could affect the game play and environment in games by touching the screen

I would like to see a fallout game on the wiiu that uses the wiiu gamepad as a pipboy.

Blatantly copied from another place. 

Tank game:
*Full 360 degree panoramic view of inside the cockpit of your tank.
*Touch screen control panel interface allows you to press the actual shiny (and sometimes big and red) buttons instead of buttons on your gamepad.


(This could be huge for flight sims game too.)

Pokemon game:
*Gamepad acts as your inventory.
*Selecting most items for you inventory opens a "mini-game" for you to use the item.
*Item uses include: sliding pokeballs along the screen towards the tv to catch/release pokemon and having a pokedex that you can use to identify on-screen pokemon.



my example of a where's wally game:

you'd have to find him amongst a crowd and take photo's of him It could have high scores where accuracy (how close to the center of the image he is) and how fast you found him increase your score. heck you could play with 2 players each using a different Wii U gamepad you could have player constantly moving around in the crowd sort of like an active hide and seek game.



other examples:

Metal gear solid Wii U:

have your communication device in your hands while playing the game.

Features:

*Rumble function while volume is on mute.
*Call in-game characters.
*Call monitoring, don't like a certain character? then don't answer.
*Text messaging for the socially awkward.
*3 built-in mini-games: Snake, Snake-man and Snake invaders.
