I think things have definitely turned around for the Wii U, especially since Mario Kart 8 came out. I finally got one for Christmas this year, but I'm a little bit disappointed. It's nothing to do with the games or the software of the Wii U, but it seems that the one I received is faulty. Whenever I unplug the console (or leave it powered down for a while - like an hour or so), the red power light starts flashing and I can't get it to turn back on. After fiddling around with the AC adaptor and the HDMI cable at the back of the console, I can get it working again, but it's a pain in the butt because so far I have to do this for nearly 10 minutes twice a day. It reminds me a little bit of the Xbox 360's red ring of death that my brother experienced. It really sucks considering I've had it for a mere 5 days, and this problem started almost immediately.
Don't get me wrong, I've gotten Mario Kart 8, Hyrule Warriors and Smash Bros. already for the system, and I'm having great fun with all of them so far, but I'm worried about playing too much on my Wii U in case it dies completely. It's a brand new console, so it shouldn't have much dust in it just yet, and when I check the console's heat after using it for a while the red light of death comes to haunt me, the Wii U itself is still pretty cold, so the fan system's working fine. I am disappointed because I expected that after so long, I thought that Nintendo would be the company to have the most reliable systems. I've got a GameCube that still works today, an N64 that still works today, a Wii that has lasted me a good five years, and a few models of the DS/3DS, none of which have died on me. My cousins also have a Wii U and it works perfectly fine for them, so it just seems that I just HAD to get the faulty one, didn't I?
I'm going to try some more troubleshooting tomorrow following some stuff I found on the internet, but if not, then it seems I'm just going to have to contact Nintendo and get it repaired or replaced. <_<
