Nintendo should task Game Freak to develop an open-world Pokemon RPG, bearing likeness to Skyrim, with implementations of Pokemon Pinball, Pokemon Snap, and Pokemon Stadium. Base the story, characters, setting, Pokemon, etc. off of R/B/Y and G/S/C.
This would solve the Wii U's sales problems overnight.
I was thinking about some great features it could have. Rather than having random encounters, you could find pokemon in the actual overworld and have to use tools and techniques in the environment to lure them out. Some would come out naturally while others would be tricky. After that you could fight them or do things like converse with them/ play minigames to win them over. It could add a great dimension to the game and really immerse the pokemon in the game world while also adding a greater sense of adventure to an already great game.
Man, I really wish they would make a real console pokemon game. It could be amazing!
