you know if the hardware power is close this kind of thing happens different games play to different hardware strengths, if wii u ports wre always superior and you have 2 that were inferior, i would agree with you but the majority are inferior, devs that have promised the wiiu version being the best have failed, cause they proabably had too much trouble cause the lack of power and said forget this is not woth the headache, you have the samething happen with 360 and ps3.

Seriously, on that one, I'm with you. The Wii, while not a complete gen above, was more capable than the XBox. No question about this one.
But the same applies to the Wii U compared to the PS4 and 360. Same ballpark, even if it's a slightly better in some aspects (GPU) while being weaker in other (CPU). Of course, the added RAM helps, but since the graphics memory bandwitdh isn't that different than what's found in the PS3 and 360, the end result isn't that much of a step up.

I think the more likely reason is that they prioritised their time and money according to expected sales; that is, they put 95% of their manpower and resources into PS3/360 and didn't invest in the Wii U version for fear it wouldn't turn a profit if they devoted too much to it.

Except that those games in Xbone/Ps4 threads are cross gen titles, never designed to take full advantage of next gen power. X is not a cross gen game. 

And WiiU as a supposed 8th gen system should have had better looking games than anything on the ps3 right at launch just like ps360 and their successors had.

And lets not pretend WKC was The best looking ps3 game in 2008. I dont see any 2014 wii u game looking better than MGS4, although Watch Dogs might prove me wrong

lets be honest a nextgen console released 7 years after 360/ps3 should run ports with out any effort. you can tell sony really went out of its way to make developers happy, now i'm not saying nintendo should do the same, but it at least be able to run 360/ps3 games with brute force alone.

Jett Rocket could not be done on Xbox. For that matter, neither could the Mario Galaxy games.

Wii fans said its graphics would improve beyond what was seen in 2006-2008, and we were proven right. Likewise, Wii U will have games that go beyond anything seen so far.

And Need for Speed and Trine 2 had no problem increasing texture resolution, effects quality, and performance over PS3/360. Because those devs actually put in a little something called effort.

@ bolded

Are you sure? Beyond Mario Galaxy I didn't really see anything significantly superior on a tech level on Wii and that came out in 2008.

As for the porting issue, Trine 2 and NFS are both simple games with a lot less going on than most of the games that got ported to Wii U. More complex games have been much harder to pull off, even when devs have said the porting process was relatively simple.
