its a god port i'm playing it rigth now.

Is not a cause to worry, the big sites are too busy reviewing all the new games coming out to generate traffic instead of just reviewing a 6 months old port that very few are interested, a few Nintendo speciallized sites will be publishing reviews WHEN the Smash one is out. From everywhere I have seen positive reactions about the quality of the port.

What makes you so sure it's Nintendo's policy?

I'm not 100% sure, but Nintendo has typically been very strict when it comes to mature content so that's why I assume they might have something to do with it. I just remember Swapnote being taken down completely because kids were sending "offensive material", no patch to fix issues or anything like that. Until someone clarifies the situation, then we really don't have any way of knowing for sure :/

Maybe it improves the cinematic feel.

Wii U doesn't allow sales to Watch Dogs.

I wouldn't be surprised if it didn't even cross their minds to allow miiverse integration. I'm just glad the game looks stable and runs well. I plan on buying it before christmas.
