I may lose friends or popularity points over this, but this game did not remotely live up to the hype for me. I've heard it described as not only revolutionary for Mario, but as "the best game on Switch" (perhaps now only to have been outdone by Tears of the Kingdom). But having not even played a ton of games on Switch, this still ranks near the bottom for me. For some context, this is my first 3D Mario platformer since Super Mario 64, a game I loved and did multiple 120 star runs in growing up, but haven't touched in a very long time.
So first, what did I like? The worlds had a decent variety. I appreciated that each of the kingdoms had its own distinct look and feel not just in its environments, but in its characters and set pieces as well. Even with this diversity of environments, the art is evocative and consistent throughout. This game also introduces a new mechanic (at least as far as I know, again, haven't played more recent Mario entries) in which you can throw your hat at an enemy and sort of "become" that enemy with a new movement style and ability. This was probably the coolest thing about the game and I liked that they extended this mechanic quite far and allowed you to use it on a very wide variety of enemies, with very few being immune to it. Though most enemies you can take over can really only do one thing, the significant variation on how you move and interact with the world with each of them was pretty neat.
What did I not like? Most everything else. The game felt surprisingly rather shallow when it came to the actual gameplay loop. Even if the worlds had nice distinct aesthetics and were objectively quite large, they didn't really feel very interesting to explore. This is due in large part to the more important issue for me: I feel like the game is purposely designed for a constant dopamine feed to the point I felt exhausted with it until it quickly lost its effect on me. Power Moons are vomited all over the map. Some have more interesting little "quests" you need to do to get them (usually those give you a pack of three) but many others are just kind of strewn about, do a butt slam here, think to look under a bridge, jump up a tiny hill, or break a shiny block. Yeah, you're constantly making progress and that may feel good in some way, but the triviality of so many of these obstacles made Mario's orgasmic moment of celebration fall flat to me after the fourth moon I grabbed in the last 3 minutes. Some moons are behind puzzles, but again, triviality robbed me of any real engagement. They're so overly simplistic, not even Aloy could spoil the solutions fast enough.
Given it's my most recent (though still quite distant) experience with this kind of game, I can't help but compare to Super Mario 64 where stars felt so much more individualized, with unique challenges that push you to explore the world's nooks and crannies. Stars in that game felt like an exciting reward and a carrot at the end of the stick for finding all the different ways to interact with the level or complete a difficult series of platforming (though to be fair, I'm well-aware that distant nostalgia has clouded my memory, it's been a long while). There's some of that here, but it weirdly feels overly streamlined to the point I never felt I had the chance to explore and appreciate the world at my own pace because 10 steps away was another "challenge" to get another "reward." It really feels like they wanted to just inundate you with so many rewards nonstop that there was little room for adding those individualized touches, at least beyond the triple packs of moons that require a specific quest. Aside from exploration, the rest of the game is fairly trivial with overly-simplistic boss fights in which the only real challenge is "do you jump on them now or throw your hat at them first?" So combat didn't add much either.
I will caveat that a lot of my qualms in the prior paragraph I felt did improve some as the game went on. I did ultimately finish it and thankfully around about Metro Kingdom (which I understand to be a highlight for most people), the triviality wasn't quite as steep and the set pieces came alive in a way I at least found more engaging. However, even in the main quest of that world, you're supposed to find some musicians and for the most part, they're just hanging out and not hard to find—especially as your map marks them for you—and each of them gives you a moon, because why not? Regardless, it was better at least and I even died once or twice to certain challenges. If the whole game were more up to this standard, I'd comfortably give it something more like 3 stars, but having to play half the game to get this point is not great, especially as it didn't feel "fixed" for me, just better than it was. I also soured on it when I saw after beating the game that the worlds were now showered with even more power moons. I just shook my head, played through the ending segments, and wandered around Mushroom Kingdom , then happily uninstalled the game.
Obviously, this game is super popular. At the time of this writing, it's #24 on Grouvee. You'll find its page littered with rather glowing reviews. While I don't really buy into any "objective" standards for games being good, it's pretty clear that this game clicked super well with its audience in a way it just didn't for me. So while I generally don't like such statements anyway, I have even less ground to say "the devs should have done X" because clearly the game did super well as it is. While I can kind of understand some of that nonstop dopamine appeal, even if it didn't work for me, I have to admit I don't quite see how it's that good for people, even reading some of those numerous quite pleased reviews. That said, I have a hard time thinking of too many things I would've liked to see different that might've made this more of a 4 or 5 star game for me, so perhaps this was more a genre issue as well. I will also grant that while I'm quite comfortable with my 2-star rating, after I clicked through my reviewed games so far, I probably like this one better than most any of my other 2-stars and it's probably somewhere between 2 and 3. With lesser known games, I often feel a little bad about being too harsh and will round up even a 2.3 or 2.4 to a 3, but I certainly don't see my honest rating hurting this game's popularity, so I'll go with my gut and say maybe these 3D Mario games just aren't for me anymore.
