But how many are there, besides those greyscale games? Nintendo have Mario, Zelda, Pikmin. They also have SEGA making new exclusive Sonic games (which look amazing), Platinum Games' The Wonderful 101 and Bayonetta 2.
I know, you have to judge both the hardware and the game content. I don't think the mediocre hardware is that much of an issue, look at what the games released so far have done (albeit there aren't so many). If you dont' want to use the gamepad to it's full potential, you don't have to. Stick the gameplay on the gamepad's screen too and you're fine.
