Generally the video starts off well and then from 15 minutes in it's downhill for me. In fact I should have really turned off 15 minutes in, and I wouldn't have so many concerns.
The 'social gaming skit' is offensive to my every sense. Is that Nintendo trying to be funny ? Is that Nintendo's idea of a hardcore gamer ? Seriously a guy who narrates every button press "on no, by button press is so ineffectual"....
Mammoth FacePalm!!!
In one 5 minute skit they basically isolated me, made me cringe but not in a 'so bad it's good' way, but just in a 'omg that is so bad it's just awful' way.
Never has a demonstration video made me never want to use a product as much as that, and I shall be having nightmares going forth

(drama queen)...
Secondly the Wii U Mii based menu system ??? WTF ??? Seriously they have to allow me to disable that. When I turn my computer/console on I do not want to be bombarded by other peoples Mii's and their comments. Seriously how long before people start drawing nob's and posting offensive words on their Mii comments.
Thirdly,
I praise the new Wii U controllers redesigned thumb sticks... BUT a bigger concern to me is the new traditional controller (360 cough), which is described in Nintendo's owns words as lighter and more comfortable for longer play sessions...

The point this seems to make to me is that the tablet controller isn't comfortable for long play sessions, and if you have the option of using a standard controller instead, how is that implemented in games ? Does that not simply cement the fact that the tablet controller and it's screen are indeed unnecessary gimmicks ? If that's the case why bother in the first place ?
The video has left me somewhat disappointed and perplexed.
Tuesday's demonstration of gaming content has some way to go to address this for me. But so far color me unimpressed.
