I purchased the Wii U on launch day, and currently own 33 Wii U retail titles. Plus more eShop and Virtual console games as well. However, I'm a strict supporter of the retail versions of games. I like having the disc and case, on my shelf, to show off. I also like being able to take the disc to friend's houses instead of taking my whole machine. Also, I like not wasting space on my HD, when I can save that for other downloadable games from the eShop or Virtual Console, or whatever. For me, the advantages of having the retail version more than outweighs the convenience of having everything digital on the machine.
Anyways, as I've said, I have a Wii U, and 33 retail titles for it. Among more eShop and Virtual Console games. That said, I absolutely love my Wii U. It's quickly becoming one of my favorite consoles. So much so, that I have officially unplugged all of my other consoles. I don't touch any other console other than the Wii U. I've put away the other systems, and haven't even thought about touching them, to be honest. Currently, I'm playing on my Wii U, 3DS, and PC. For me, I'm set. I don't need any other gaming machines.
So, personally, I highly recommend the Wii U to you. In fact, I recommend it for everybody. It has a lot of good stuff for it already, and, it's got a lot of great stuff coming out for it soon too. And that's just what we know about. I'm sure that there are still lots of surprises for it yet to be announced. There is a lot of excitement around the Wii U, and the future is bright. As for the PS4 or XO, most of the games on them I want on either the Wii U or PC. There's really nothing on those systems that scream out "You must buy me now". Nothing. Like I said, the games that interest me from those systems I either want on the Wii U or the PC. So I have no desire to get a PS4 or XO anytime soon. Maybe next Christmas. I'll look at both of those systems then, and see what they have to offer next year. If it looks interesting or worthwhile, I may finally jump on board then. But in the meantime, I'm not even worried about them in the slightest. I'm far more focused on my Wii U, 3DS, and PC. Instead of spending several hundred on the PS4 or XO, just to have it sit there and never touch it, I'd rather spend that same amount of money on games for the Wii U, 3DS, and PC. And I'd probably need more money than that, given how big the list of games is that I want for all 3 systems. I can think of about 20 more Wii U games alone that I want, which will be out between now and Spring 2014.
But yeah, after playing the Wii U, I'm in love with it. I think it's great, and highly recommend it. As I've said, I play it so much that I've already disconnected all of my other systems. The Wii U is the only console that I have plugged in. And, I've already taken it on several road trips with me, playing on the Gamepad while in the car or on the train. Didn't play it on the plane tho. But the train had an outlet, so I got to play it on the train. And I have the adapter to plug it in the car. So roadtrips were fun with the Wii U.
Currently I have 33 retail Wii U titles, and 40 retail 3DS titles. But since you asked about the Wii U, I'll list the Wii U titles that I have. Feel free to ask any question you want about any of the games, and I'll answer to the best of my ability...
