If it didn't come with the console, Nintendo Land is great for local multiplayer.

Super Mario 3D World.
GOTY 2013.

Wii Sports Club Tennis and/or Golf license.

Nyko Pro Commander is a great piece of Kit for the price. I would put it on par with the Nintendo pro controller, but it suits different people. Surely worth trying it.

Did anyone else notice how supportive, helpful and friendly Wii U owners seem to be in a setting like this?

I also recommend Lego City Undercover! I played it for over 100 hours last year so that must mean something. Really refreshing open world game.

I'm sure if anyone posted here that they bought a Xbox 1 or PS4 and asked for recommendations members from their communities would give games that they were enjoying too.

The majority of the time I hear complainers bemoaning everything and anything, especially people who see the word nintendo and come to have a troll.

Further, when I owned a PS3, 50% of the advice I received or conversations I had involved rudeness, xenophobia, swear words or immaturity. When I mentioned WII U owners, I wasn't specifically speaking of this forum. I was speaking in general terms.

oh yeah that's fair enough, if you see sites like N4g I know there the fan base is fairly crazy Sony biased but here on VGchartz there is a decent community for all 3 systems so when it's a thread about just 1 machine there is normally a good chat about just that system, when there's some multiplatform that has either DLC on one system or a better frame rate on another tho you can see some pretty nasty stuff kicking off at times, if you wanna see the worst of it tho you can do a search by users who are currently banned and read what they did to get it, I read it for fun at times :D
