The Wii wasn't a flop at all. It had a lot of very unique and fun games. Not as many bigger titles as the other systems, sure. But it still held it's own. Even if most places didn't want to give credit where credit is due. Tho, now that the Wii U is out, I see a lot more places online trying to show the "best" Wii games, now that it's being phased out. The Wii was far better than 3rd parties gave it credit for. It wasn't as powerful as the other systems, but it was far more unique, and could do all kinds of great things that the other systems couldn't. However, because most 3rd Parties showed to be unimaginative, they blew it, when it came to the Wii. They did, they blew it. They didn't treat it seriously, and gave up on it before giving it a chance. Some did great things on it, but overall, for the most part, they treat it seriously, and thus, missed out on all kinds of potential hits. Their loss.
As for the Wii U, oh man, this is quickly becoming my favorite console of all time. It's not quite there yet, but oh man, is this system awesome. I bought it on launch day, because I saw the potential for it then. And now, almost a full year later, it still hasn't quite reached that potential, however, it's come a lot farther in it's first year than the Wii did. Sure, the Wii had more titles overall in the first year. However, the Wii U has more bigger titles, as well as a lot of fun and unique titles too. And new IP's are on the way. More big titles are on the way. More surprises are on the way. Tons and tons of indie games are on the way. This new system is definitely my gaming console of choice. In fact, the Wii U has proven to be so awesome, and so full of potential, that I have no plans on buying a PS4 or XO. None. I'll look at those two systems next year, around Christmas time, after they have been out for a year. But they mostly seem boring to me. No fun. No imagination. And a lot of the same things that they've continuously done over and over. Nothing exciting for me from there, as most of the games that I want that will be on those systems, I would much, much rather have on the Wii U or PC. The Wii U, on the other hand, looks amazing, plays great, and is tons of fun. Currently, the Wii U is my absolute favorite console to game on. So much so, that I unplugged my other systems, and the Wii U is currently the ONLY system that I have plugged in. Not counting my 3DS and PC, of course. But I've hardly touched those since the Wii U came out. Gaming wise, that is.
If Sony keeps showing off what they have been showing off for months now, and if Microsoft keeps showing off what they have been showing off for months now, and if Nintendo keeps doing what they have been doing for months now,... then I am absolutely sticking with Nintendo. They are on the right path, doing the right things, and headed in the right direction. I love what Nintendo is doing with the Wii U. It brought excitement back to gaming. As a gamer, I am excited to be a gamer again, and it's all thanks to Nintendo.
The Wii was fun, but the lack of 3rd Party support hurt it's longevity. And the 360 and PS3, tho both had their moments, got stale and boring after a while. I think the 360, PS3, and Wii generation, was the worst generation so far. I mean, yeah, they had a ton of great games. However, a lot of things I didn't like also came out of this generation. For instance, genres became way, way over saturated. Everybody made all kinds of the same games. Whether they be first person shooters or 3rd Person action, or whatever. Way, way, too many games felt the same, and kept trying to do the same things or copy each other. They all felt the same. Also, shovelware became way more abundant across all systems (mostly on the Wii, but across all systems too). I mean, there has always been shovelware on consoles, but this past generation saw more than any other generation. On disk DLC is ridiculous, and got ever so popular this generation. Speaking of which, more and more ways of companies trying to squeeze money out of you got more rampant this generation than any other. Also, pre-order dlc dumb too. I think the idea of being punished for not pre-ordering a game is stupid. You shouldn't be punished by not being able to access parts of the games or features of a game, just because you didn't pre-order it. Pre-ordering and getting a physical item, like a toy or figure or something, is one thing. That's cool. But to get access to parts of the game that others won't be allowed to access, just because you pre-ordered it, is ridiculous. That's a dumb idea. Speaking of dumb.. Fanboy-ism also was the most rampant to the extreme this generation too, which was just horrible. I'm not a fanboy, myself. I'm just a "gamer". I like games of all shapes and sizes, and platforms. I was a huge Playstation fan for a long time, as they had my favorite games during the PS1 and PS2 days, however, I still played the other consoles. Now, I favor Nintendo, but I still like the others and will play them. I don't play them much anymore because I'm bored with them. But if they become fun again, absolutely I will play them and praise them. Fanboy-ism is retarded. A true gamer is one who will play all games, regardless of console. Another thing this generation is tacked on features. Like, motion control, for example. It's one thing to build the game from the ground up around the controls. But it's another thing to tack it on at the last second before releasing it. At that point, why bother. 3rd Parties really fell on their face when it came to that. And not just on the Wii, but with the Kinect and Move as well. Which, brings up laziness. Lots of laziness in the gaming world this past generation. Tho that kind of covers a broad area of this. But there's more... I could go on and on, but I'll stop here.
In the end, I'm glad that this generation is ending. I've been gaming since the early 80's, and this past generation is by far the worst I have ever seen. In fact, this console generation had made my a full time handheld gamer. The DS was amazing, and I played my DS far, far more than the 360, PS3, Wii, and PSP, combined. Seriously. The DS got way, way more game time played on it than the other systems Only the PC got more game time. I did play that a lot, because all 3 consoles weren't enough for me. I needed more. As a gamer, I needed more, but more importantly, I needed better and more fun games and consoles.
And who was the first one to offer something better. Nintendo. With the Wii U. The Wii U is amazing. It's super powerful (more so than most people seem to give it credit for), and looks great, it controls great, and the Gamepad is one of the most convenient and fun things to happen to gaming in a long time. The PS4, and XO, as much as I'd like to play them, feel boring, and "more of the same". So, I want to wait on those, to see how those actually turn out, before I rush out and get them. I'll get to play them, as I know people who will get them. But I'll wait until I can play them myself and see what they are all about. In the meantime, the Wii U has already gotten me back into console gaming again. As a long time gamer, I'm excited again. I haven't been excited to be a gamer in a long time. This whole past generation got worse and worse and worse, then a little better, here and there. But overall, the last generation lost me as a longtime gamer. But the Wii U brought me back, and I am so, so excited for the future. The Wii U has a truly bright future, and I can't wait for all that's to come with it. It's constantly getting more and better things for it all of the time.
So, already, this generation coming up is already looking to be far better than the last generation. The Wii U, PS4, and XO generation is looking to be an overall better generation than the Wii, PS3, and 360 generation. That generation, as a whole, was terrible. However, while Nintendo seems to be pushing the industry forward, to newer, and better things, Sony and Microsoft still seem to be lifting the industry upwards. Both need to happen. Upwards and Onwards is good. However, you can only go so high before you get boring, and come back down. You need to go forward too. Something Sony and Microsoft didn't really do too much this past generation. So I'm a bit skeptical on them going into this generation. I hope they prove me wrong, and turn out great. I'm still in a wait and see mode on them. I don't' want to get burned by them. So I'm waiting for a full year before I decide on them. In the meantime, I'll be enjoying my Wii U.
So, to answer your question.. "do you prefer the wii u over any other console?"... why yes... yes I do. Currently.
