I own a Wii U, and I own 5 titles for it. I've owned the system for a couple of weeks and have put around 50 hours into it.
I will be honest, do not believe a word or text article you read concerning the Wii U from the gaming media. There is so much bad information and just flat out wrong information out there concerning the Wii U, the media practically wants gamers to hate it.
They overblow mediocre titles and make them seem like triple A knockouts just because they won't be coming to Wii U. They make really good titles for the Wii U seem average at best.
They said Lego City requires an external harddrive, nope, it doesn't. If you own the black one at least. They said the load times for it were horribly long, besides the first initial load taking roughly a minute, I've never come across load times that were just unbearable.
Please, I beg you guys, do not read anything about the Wii U from sources like IGN or Gamespot or any mainstream review website. I can promise you all they are doing is making the WIi U seem like it's the worst system ever and Nintendo is on it's last leg. These sites sleep in the same bed as EA, Sony, Microsoft, Activision, and a whole lot of others.
