Huh?? Just no.NOPE!
Graphics- Gamecube was the most well rounded and impressive nintendo system graphically respective for its time
Games- Gamecube and SNES absolutely shit all over the Wii U in terms of the amount of quality experiences they had in their first 2 years.
Edit:The only thing the Wii U has is above all other Nintendo systems is its backwards compatibility. actually that goes to the wii because gamecube titles
The Wii U is just a slightly underwhelming mixture of the gamecube and the wii.
