I'm not happy about any of them flopping to be honest. The industry needs Nintendo as they serve a noble purpose imo.

Sonic Boom :p

Amiibo Festival definitely deserved to flop, and even if I'm sad for its fate, the digital-only launch by NoA of Fatal Frame V made it a game deserving to flop as well, at least in America.

The one that saddens me the most is The Wonderful 101, it's one of the best, if not the best game I've played on my Wii U.

Damn, did you really just went there?!

Amiibo Festive was the only game recently to actually make me angry with how it was being sold so I'm glad to see that it didn't do so well. Other than that I'm pretty indifferent however it was sad to see Wonderful 101 and Fatal Frame flop, those game deserved better.

Sonic Boom, Animal Crossing: Amiibo Festival, and quite a few lazy/late ports the Wii U receive over the years.

I'm guessing it was meant as a joke. "Hyrule Warriors" was barely playable.

It's been my only trade-in on the Wii U thus far.

I assure you my good sir, I was not joking.

For all its obvious flaws, I found Hyrule Warriors a pleasant slice of mindless, therapeutic mayhem. Wind Waker I couldn't even bring myself to finish.

I have to agree on this. I loved Hyrule Warriors for what it was, it's the most played game on my wii u, even if I haven't played it for more than five months. Wind Waker was fun but I found it boring compared to other Zelda games. Also, I thought HW ww sales were 1 million and Wind Waker around 1,6?

On topic, I'm not exactly happy that some of those games bomb, if only the opposite.

It saddens me that Fatal Frame V, Bayonetta 2, The Wonderful 101, Zombi U sold less than they deserved. Oh! And I agree with Injustice, it's a fantastic game I bought it for 11€ and I loved it, it really impressed me.

The only game that I think "deserves" its sales is Animal Crossing but mainly because I wanted a real AC game, and also because it's overpriced for what it is. 

Splatoon, mariokart, smash bros, 3d world and new super mario bors
