On Mario Kart 8 there is nothing wrong. I'm sure none of the Mario Kart player with huge experience, but it's fun to me yet. The cards are nicely designed, the drivability is good and you can tell that because love is in there. The multiplayer will also work very well (except for some minor connection problems, but probably lie at launch) and the direct comparison with the other players motivated additionally. Do I have much else to say about Mario Kart? It works well, it's fun ... I think that's enough.
For Wii U itself: I have in front of not much concerned with it, and do it not even now really. Mir is only noticed that everything works very well. For this purpose it is actually easy to use. What surprised me the Internet Web browser that does really work very well and smoothly. Even complex pages are loaded quickly and play videos, texts in forums write etc. presents no problems represents the Nintendo Network also seems to be simple and work well -., It is also still free. The battery of the gamepad is fast empty, but the screen is really worth it. So one must not necessarily look at the screen or can there also run something else (Wii U needs to be near the gamepad).
The action with the additional free game has also worked well. After registering in the Club Nintendo I could download it already.
I have long doubted the Wii U, but decided by Mario Kart 8 for sale. Alone for Mario Kart 8, it has actually been paid - through the extra game anyway. But not only Mario Kart 8 convinced me, but also the Wii U as the system itself. Everything works fast, simple and hassle free.
Who makes fun Mario Kart and who are considering buying the Wii U should really get this one. I must say though, as "master console" I would not use the Wii U, but it represents the perfect addition to PS3 / 4, Xbox 360 / One because it simply offers other games as just mentioned consoles.
