Flop?

A game can flop when it comes to costumer satisfaction, even though it sold well.. Just like the new iphone. The costumers not happy.

Well, customers don't want the Wii U, that's pretty much clear. They want 3rd party software and will buy only machines that will get all these games.

Despite all that, your analysis is subjective and isn't counting titles that people really enjoyed on PS4/X1 like Shadow of Mordor, Need for Speed Rivals, Fifa, The Last of Us, Metro Redux, Assassin's Creed 4. Titanfall was a critical and commercial success and it has a higher meta than most Wii U games you showed. Actually, TLOU Remastered has a bigger meta than any Wii U game ever. And saying that good sales aren't related with consumer satisfaction is trusting on anecdotal evidence. Usually higher sales are reated with games that the consumers want and like.

We can really extend this analysis and say that PS4 consumers are probably way more satisfied since people keep buying it. If it was underwhelming, people would stop buying it for the bad word of mouth. So people are buying what they enjoy more, simple as it is.

Those Wii U games only satisfied Nintendo fans, that's why they bought the console in the first place. In the case of ps4 and xbox one owners, some multiplatform games underperformed critically speaking but that will be fix with games like Assassin's creed unity, far cry 4 and many other games..

"destiny..... Sold well... Most were left with bad taste in their mouth."

Source? Is it the fact that 3.2m players play it daily?

Ok bud lets look 2014

The year of major dissapointment for the wiiu and its fans, its game droughts and constant game failures critically and market wise.  With the exception of Kart, everything on the wiiu underwhelmed underpreformed or flat out flop like Wonderfull and even DK.  No 3rd parties and the few that were promised were delayed and or never heard from agian, a year where sports barely exists on the platform.

As far as dissapoinments between the big 3 there is no bigger one then the wiiu in 2014.  

"why do ps4 sell so well when the games do not satisfy the costumers? And why dont wii u sell better when people are much more satisfied with the software?"

Nothing supports your two statements here. In fact, sales actually support the exact reverse of what you're asking.

Judging from the rest of the post, make believe? Hopes and dreams? Drug induced visions? Idk. As an Xbone owner I have played many good games this year.

Was the guy's profile picture a panda?

Some even "flop" at understanding OP point and talks about the non existent multiplatform support for Wii U.

Anyway, OP, there are 3 reasons:

1. It is hard to compete with Nintendo in the quality realm.
2. There are no more games, therefore whatever you have is going to be like water in the desert. But this water is delicious.
3. Some have lower standards and many games are "good".
