I wouldn't argue against the Wii U's library being quality, but it was either so derivative, safe and bland, unnecessarily obtuse, or soon to be surpassed by the next iteration I don't understand why it gets as lauded as it does. It's fine, and for many companies it would be well above average, but frankly I find it BY FAR the least resonating library of a Nintendo console. I think every other Nintendo console since the NES provided us with software that pushed the envelope more and had a greater impact than the Wii U's offerings.
The only exceptions (imo - and not counting BotW) are Splatoon, Super Mario Maker, and maybe Nintendo Land (which Nintendo mishandled). And as far as legacy goes, I don't see any games other than the former two being widely canonized. Like in 10 years, how many Wii U games do you think are going to make "greatest games" lists?
I don't think that's exclusive to Taiwan...
