If somebody only owns a Wii U that is a non-issue to them, just like those who played RE4 on the PS2 didn't lose out by not playing the better version on the GC and the best version on the Wii. I can say the same thing about my PC versions of multiplatform games in regards to the PS4/XBO, as well. Having said that, there are ways in which the Wii U version can be better on a case by case basis - framerate, tablet controls/off-screen play, etc, etc. Graphics (for scaleable games) are only one aspect a game can be better. Personally I'd rather play shooters on the Wii U than the PS4/XBO (assuming I didn't have a PC) for Wiimote controls alone. 

Maybe you and few people stuck in the past but most people I talk to don't like that.  Personally I hate playing this kind of game with Wiimote, and Nintendo isn't even pushing Wiimote play anymore.

For Nintendo fans there is a significant group who expressed their pleasure with the WIimote's IR function for shooting games. Even if NIntendo doesn't push it, FPS games for the WIi U still support the Wiimote. Dual Analog for shooting games is so archaic for PC games and Wii gamers alike. 

Examples?

I think Gamecube had a lot more AAAs than Wii U in the same time frame.

Assassin's Creed, Mass Effect, Call of Duty, Deus Ex, Watchdogs, Darksiders (not sure if AAA), Batman, Rayman, Dragon Quest, Monster Hunter are all big series/titles that have come to the Wii U. 

DQ & MH are for Japan only for now.  Watchdogs isn't out yet.  ME/Deus/Darksiders Gen 7 ports but that's fine.

Monster Hunter G (Crystal Chronicles was only released in Japan in 2003.) 

Wii U will sell 10,5 million by end of year, and will increase the sales next year.

"Octimist", no, you hope this number but even you know that will sell more. :3

what are these cases? cause as someone said if there is a PS4 x1 version its automatically not going to be the best version be default. You gonna really say AC4 was the best on WIi U? Lets be real about the tablet, 3rd parties hell even Ninty doesnt really use it in anyway. so that is mostly negated. You named about two games that we could argue about that are better on Wii U...TWO. thats not alot NFS and Deus Ex and even then its negated because they are late ports, in the case of the latter it was REALLY late. Youd rather play shooters on WIi U than PS4/X1? How is that possible when the system barely has any shooters, besides COD which even then the online isnt as good, it doesnt run as good and has missing stuff. Seriously doubt wiimote controls are gonna offset all of that. If you only have a Wii U it doesnt matter but on this site you would think it would.

In other words less than GC, thanks.

Shovel Night?  Duck Tales?  I didn't include all the games so that you could start including a bunch of indies and crap.  I think you can find over 10 games on that list of 50+ that are big AAA.
