Unfortunately, this study isn't really of any relevance. Most of Wii Us decent games are exclusive, and most games on the other consoles are not. Wii U doesn't get a lot of the good non-exclusives, where as PS4 gets all of them. In addition, when it comes to non-exclusives, none of Wii U's are the definitive version of the game, whereas PS4 has most to all of the definitive versions of non-exclusives. Non-exclusives on PS4 count for a much larger number of games than exclusives on Wii.
This is why the Wii U does not look like an interesting system to most, the library is sparse, and the only way to make it look decent is by really skewing the numbers this way, and that cuts out LOTS of relevant information. It's a meaningless analysis.
I describe myself as a little dose of toxic masculinity.
