Its not lazy, the teams that handle ports are the bottom of the barrel. They typically have the least/no experience which is why they dont actually make games, but simply port games other people make.
So not only do they not have the experience or knowledge to make use of something different than what they are used too, they have no idea what makes the engine they are porting really tick and cant dive deep into it for of screwing it up.
Take a look at the who said what. 99.99% of the time the scenario goes like this:
Wii u hard/weak: Comment made from/derived from port team that only knows how to use middleware engines and tools provided to them.
Wii u actually pretty powerful: experienced devs known to make their own engines/tools.
But it doesnt really matter any more. Screens of pikmin 3 are flooding miiverse, the cats out of the bag. Anyone with eyes is starting to notice the weak narrative about the wii u is full of crap.
Now im just waiting for big name western 3rd parties to once again, show everybody why I dont buy them on Nintendo systems. They release second rate crap for nintendo systems. And I dont buy crap.
Well. That was disheartening. Not false. Just disheartening.
