I think the best option.for Nintendo would be something similar, yet totally different.
Puzzle pieces.
Each game, instead of Trophies or Achievements, has a Jigsaw-like puzzle to it. Instead of getting a trophy or a little number, you get a puzzle piece. You use the Wii U Gamepad to put the pieces together.
Instead of a total Gamerscore or Trophy level... It manages the total puzzle pieces you have along with completed puzzles that each game has.
