Question: are wii games better on wii u?
Answer: Nintendo Reconfirms Wii U Will Not Make Wii Games Sharper Upscaling means taking a native image and fitting it to your screen. If the console didn't do it, your TV would. However, the Wii U internal scaler is quite good, and because of that and hdmi producing better colors, wii games do look better *upscaled* on Wii U.
