Looking back, it almost feels like a Switch prototype. It's a goofy little thing, but I love it. That said, I also love the Nintendo Virtual Boy, so my judgement might be questionable.

I agree. I think the problem with it is that it was just too complicated. With most Nintendo system what you see is what you get - with the Wii, those people having a good time swinging around their little Toblerones really are playing a game; the Switch really is a home console grade portable handheld thing; the WiiU manages to look like both those things without being either.

I'm a bit confused why it never really caught on. It had so much potential. I loved playing a game while having the map on the little screen for example. Or the inventory or whatever.

Thank you! I think the impracticality of it all adds an extra layer of fun :-)

Eeeehhhhh...

There are dozens of us!

Slightly perceptible, but totally playable. Considering all the hops it has to make, it's surprisingly good. I have both my WiiU and my desktop hooked up to ethernet, which helps. Games like Portal 2 work well because they don't usually require split second inputs, but anything requiring precision (like a rhythm game) would probably be a struggle.

negligible compared to the pal display and jet engine noise?

Most definitely!

Neat! Nah, I haven't done the USB C mod, but that looks pretty slick. I just use the charging cradle that came with the black WiiU deluxe set.
