The online is fine, the problem is that not many games utilize it...

Also, I think that NSMBU actually looks pretty pleasant, and it is a huge step up from NSMBwii...especially when it has levels like this (although I think the normal levels look nice too):

Granted it isn't mind blowing or anything, but it is pleasant and simple and clean and it works...

My first three ganes have been MK8; Pikmin 3, and Child of Light. I have no bad things to say about my Wii U so far!

Right, well to answer your questions first.

1.) They are tied to your console yes, but they are also tied to your NNID. So should you buy a newer Wii U, you can transfer the console if you call Nintendo (although Nintendo still has to add the account transfer system for Wii U, planned feature) They aren't changing this up any time soon, I guarantee that. But most every game you can buy at retail so just buy there.

2.) The online is solid and works much better than it did in the Wii days. People love to compare it to the Wii but it's not the Wii. They have a lot of modern features that Sony took 4 years to implement, thankfully when these features are implemented they are solid and easy to use. Some of these features the Wii U has you need PS+ to actually have (automatic patch download/installs). The fact they are the first of the 3 to make an actual social network says a lot more in favour of their competence with the online world. All this wasn't rush, but all this still will take time to evolve. All this is free too, but in an interview I read they are looking in to the idea of subscription models for things. Most people who say that the online isn't up to par needs to get a life as they either don't own a Wii U or think that trophies and cross game chat is the best thing in the world that the Wii U needs that trash too.

As for your remark about people who bought launch consoles, I take offense to that as a launch console owner. There was plenty to keep me occupied. Monster Hunter was my life for several months. I played and enjoyed NSMBU as the controls were much better and had no input delay (the HD difference). I enjoyed it and it did look like a nice HD rendition of Mario. Nintendo had problems because of their quality bar which is set extremely high. I really don't want shitty Nintendo games, no one does. Besides you had other choices of games, I wouldn't have recommended that over Pikmin 3 and Legend of Zelda Windwaker HD

Glad you like it.

I bought my Wii U with Christmas and in the begin I didn't play that much (Not that much games), but now I play almost daily. I play alot of Mario Kart 8 and still have to play the free game (Pikmin 3) for the first time xD
Also have some other 3rd party games for when I get bored.

Should have used your free game code on Wind Waker or Pikman 3.

If you think that NSMB U and NSMB Wii look even remotely similar you need to have your eyes checked out. Of course a 3D game such as Mario Kart 8 or Super Mario 3D World is going to look better but plug in your Wii and switch between them - there's a HUUUUUGE difference between the two.

Go pick up 3D world right now.
its a masterpiece.

I have the same problem.  Everything I play on Wiiu is working like a charm and it has Miiverse.  How exactly does the WiiU have bad online rofl.

It is better online imho because its free and it has miiverse.

Don't forget to watch porn on the GamePad!

Im glad you like it. It´s an amazing console.
