Why do Wii U Owners Not Buy 3rd Party Games?

[Poliwrathlord]

Why do Wii U owners not buy 3rd party games? Seriously, why don't they? I think sales for a lot of 3rd party game are terrible. Here are some examples:

 

Injustice: Gods Among Us - .08 M. Global

Tom Clancy's Splinter Cell: Blacklist - .05 M. Global

Call of Duty: Ghosts - .15M Global

Even Rayman Legends, a game orginally made for WiI U and is the best experience on Wii U hasn't had to great of numbers:

Rayman Legends -.32 M. Global

 

I know that Nintendo Fans, myself included, prefer Nintendo games, but with the lack of Nintendo games on the Wii U why not buy these games.

By the way I have seven 3rd party games in my Wii U collection of sixteen games so I don't know if that makes me part of the problem.
