Do You Believe Wii U's Userbase in Japan needs to buy more variety?

[OfficerRaichu15]

Most of Nintendo's titles are sadly bombing/underperforming in Japan on Wii u.

What the hell are these wii u owners playing then?

For Example:

The only titles over 25% in attach rate in Japan are as follows

MK8

SSB

WPU: got lucky due to a great bundle

SM3DW

NSBU

Now Lets look at the titles that you could consider bombs by going by media create/famitusu

DK Tropical Freeze: 35k(lowest in series debut)

Dragon Quest 10: 44k(wins lowest in series debut by a lot)

Kirby and the RC: 32k(2nd lowest in series debut)

Mario Party 10: 50k(lowest in series debut)

Bayonetta 2: 38k Debuted higher on the 360(a dead console in JP) with less than 1 million install base vs a 1.7 million install base

Fatal Frame 5: 38k Luckily for this most of its games debut around its number

Captain Toad: 28k(got lucky due to holidays for its legs)

These are few of the many examples of games that have underperformed in Japan.

So I ask you this 

do they need more variety and what do you think they use there wii us for if they oly buy(most of them) 3 games on it?
