Easily one of the best Mario games I've ever played, and certainly one of the best Mario ROM hacks I've ever played. Hell, I'd almost even put this over Super Mario: Star Road. The creativity, the charm, the well-designed levels, even the new additions such as the shops and the new challenge houses are all well-made and thought out. I can say without a single doubt that these creators understand Mario and it's design better than almost anyone else. The only things I can think to criticize are the visuals, the re-used bosses, and the absurd difficulty spike that occurs after you reach the space levels – Like you can feel the game go from "normal" to "hard" very quickly, and it just keeps going until near the end where it reaches "testicular torsion." But even there, the game still feels relatively fair, and if you bother to look for the switches and shortcuts, the difficulty can at least be lessened.

But the biggest compliment I can give this game, and the one I'll leave off on, is the sheer sense of adventure the mostly inter-connected world map provides. I'd recommend this game to anyone who enjoys Mario (and who doesn't?) for the sense of adventure alone. Even if not all of the ideas are good, the game never stops trying new and creative things. And I love it for that.

A surprisingly neat ROM hack with a lot of heart put into it, at least way more than the vanilla NSMB games nowadays, anyways.
The level design here is definitely one of the biggest highlights of the game, they are really varied in terms of structure, and many of them have an exclusive gimmick per world, which are really good considering the limited editing tools back in the day.
The music was pretty okay most of the time, but sadly not much past that imo. There were some pretty nice original tunes like "Underwater" or "Fire" but even then, they are not very memorable. Other than that, I also detected a lot of rearrangements of soundtracks from other mario games, like Yoshi's Island, NSMB DS and even damn Wario World, and they are... not that good, I'm sorry :(

Overall, definitely the best New SMB Wii ROMhack out there, and also one I have a lot of respect for, even though I'm not in love with everything it has to offer. Hopefully there will be more updates about the upcoming Newer Deluxe version soon!

Its best moments can make for some actually intense, precise platforming, but overall it's just too inconsistent in its level design and its construction to be worthy of a serious recommendation.

At the end of the day, I think NSMBWii was a very flawed foundation to work off of, and while Newer tries its best to make something a bit more thoughtful out of its template, it just feels like Mario Maker-tier level design too often, unfortunately.

It's a technical marvel, but as a certain washed-up YouTuber says:
"So is the cotton gym, but I wouldn't take it with me on the car!"

EDIT 09:08/2021: holy hell if this game doesn't have too much content for its own good. i would have rather seen half the number of levels with double the polish

A bit surprised to see this on here. I've followed the Newer devs for quite a while and they're pretty good at what they do. This is a mod for New Super Mario Bros. Wii, as the title implies. A lot of work definitely went into it, which can clearly be seen through the various new enemies, worlds, levels and the addition of a new power-up. Newer Wii is significantly more difficult than the original game, clearly meant to be a mod created for more hardcore fans of the series. I myself found it sometimes a bit difficult to complete, but I liked it. It was about what I wanted from a New Super Mario Bros. game, albeit with a few bugs and missing quality of life changes.

Absolutely mind-blowing that this is a fan game. It takes everything from the original New Super Mario Bros. Wii (NSMBW) and elevates it. New powerups, new enemies, new level themes and it all comes together so well. My only wish is that it were a little more difficult, but I can't really complain since it's meant to feel similar to an official sequel and this is definitely harder than the original.

While it's still the normal NSB gameplay, this unofficial release is a stronger entry than the original NSMB Wii, in my opinion.

For a mod of NSMBW, dang this game kicks ass! The attention to detail and the meticulous game design makes it very genuine and a very fun game in the end!
Like, this mod has a whole new map that looks magnificient all together, a TON of new textures, enemy retexture, new level themes (like a whole world being in a forest in autumn, another being IN SPACE, WITH THE LOW GRAVITY, HOW COOL IS THAT?!?!), addition of Shy guys all together with ballon shy guys, jumpy shy guys, and more, new unique boss fights that are a bit more difficult to win than in the original game (and then there's the koopalings, which are a joke to beat), new mechanics in each level (like giant pipes, the hammer powerup to beat boos, a train level with gaz smoke that kills you, and so so so so SO much more
There's fricking over 400+ star coins to get!!
And also Lakitu owns a shop now.
AND ALSO MUSIC REMIXES FROM OTHER GAMES!!!
and also new yoshi recolors.

The only BIG default with this mod is that the difficulty is... nonexistent for most of the game (you would lose some lives, but you're really always gonna have ~95 lives on you most of the time) and then comes the 7th world and... Giant difficulty spike.
I swear, I might have lost like a good chunk of lives on one specific level in World 7, then comes the 8th world and it goes back to low. Even the bonus and secret worlds are going without a big hard block!
And also some of the music used is... passable. Some of them are really feeling it's a mod. The boss fight music, or one for main levels (which I think is a remix of World 6th map music in the original game) are really off.

Nevertheless, god DANG it's a good game.

I honestly adored my time with this game while playing co-op with my girlfriend! Yeah there are some funny bits to it thanks to being a fan made game, but the level design was really fun and engaging with many different concepts and ideas used, probably more honestly than any of the official NSMB games. The difficulty isn't very high but some stages in the last two worlds were pretty intense gauntlets, and I think the difficulty curve is really smooth. Also REALLY enjoyed the music, which I was surprised to learn was done by the team themselves! This was the hack I've played all the way through for a game but I think it was lovely.
