Looking at the Wii-U, while it hasn't sold well at all due to its lack of a game library, I personally believe the innovation of the Gamepad was a great idea. It works well with many games while offering a second screen to play on when your television is in use. I personally believe that the Gamepad design has many more great uses left in it, but I don't think that it should be a requirement for games as the Wii-U has used it for. I feel that it would be a great optional controller for games of the next generation. Ideally, while every game would be fully playable with the controller standard, using a Gamepad could add a useful but optional feature to each game, much like the items menu being on the Gamepad and such. What do you guys think?
