Screen settings on the Wii U are kinda janky. The picture actually goes beyond my TV's borders. Individual apps have a fix for this, but there's not a general one for the system so all of my games are displaying with about 10% of the picture being offscreen. Luckily this hasn't hurt any games yet, in fact, NSMBU actually displays just fine (almost perfectly!). Hopefully a patch fixes it though. Some TVs can fix it just through their general settings, but mine does not have the option
Oh God, really? That definitely sounds a little iffy to me. Hopefully something can be done about it. Usually there is a setting on the television, and I was going to suggest that until you said yours didn't. So yeah, bummer to hear that, but happy to hear you're liking it!
Also, best 2D Mario Platformer of the decade, eh? Interesting... *rubs hands together, licks lips*
I've had no problems with the screen pictures at all. Then too, the ability to fix this is something that should be in the system settings, so if it is not there, then that is a problem. As for NSMBU, I agree that it is possibly the best 2D Mario game in a long time (I wouldn't say decade without a complete list for reference). It felt like a very polished NSMBW that is certainly worth the upgrade. I also really enjoy being able to issue challenges to Miiverse friends on Challenge mode and having the added Boost playing option on mulitplayer. I think those will add more replay value to this game compared to other Mario games that have little incentive to continue playing past the week it takes you to unlock everything.
