I'm about 70% through New Super Mario Bros U, but I honestly don't see it changing much so I may as well give my thoughts now.
Of course, there's not much to say about the gameplay. This is basically Super Mario in HD, so I won't waste your time. If you've played any Mario game after Super Mario Bros 3 you've basically played this. Still, there's a reason that they keep making these games, and that's because they're good and they sell well. And this game is good. Doesn't deviate much from the formula, but that's good to keep working with a good thing.
The one thing I have to give Nintendo credit for is they finally brought back the challenge to Mario. When I played the last game (New Super Mario Bros Wii)
nearly 5 years ago, I was disappointed because I felt the game was too easy. Well this time they really upped the difficulty. It's been a while since I've been so frustrated by a game, but like the recent Rayman games, it's a fun frustration, where you KNOW you can beat it if you just keep trying.
Still, Nintendo is once again committing the sin of just refusing to evolve with the times. As I said, the formula is an oldie but goodie, but it's still old. And sadly it's showing it's age compared to other modern games. We're still using the same power ups that we've used since 1985, and they're actually still using the same SOUND EFFECTS as 1985! There's more nostalgia on display than at a high school reunion from an 80's class.
Perhaps the biggest offender of "won't let go" is Mario's insistence on still using the goddamn lives system. What's most insulting is that even Nintendo doesn't seem to like it anymore but are bound to it, so they throw one ups at you like modern parents throw undeserved accolades on their children. I have over 70 lives right now on my save game, but that of course doesn't include all the lives I've lost so far (and believe me I've lost a lot of them.) So why not just abandon them already? Just give us infinite lives. I mean, if we can save the game progress, what point is there to the lives system?
The other complaint I have is with the revised inventory system. The last New Super Mario game let you carry an absurd amount of items, so I understand Nintendo deciding to limit to about 10 items. However, what I DON'T understand is why they force you to abandon an item if you get a new one and you're full. Why not just let me use an item to free up a spot? Don't make me play Sophie's choice with my items!
So in conclusion, New Super Mario Bros U is another winning entry in the classic Mario Series. However, with each release that wire it walks between "Nostalgia" and "Played Out" gets thinner and thinner, and competition from Rayman and the Indie scene is throwing projectiles and getting closer and closer to knocking him off. I hope Nintendo can mix things up similar to what they did with Mario Galaxy (which they then basically abandoned after SMG 2) but we'll see what happens. I give it a B+.
