Gonna make a small break in my retirement from Smashboards to share some thoughts I had.
Firstly, while I heavily prefer All Star Brawl, I do recognize that Multiversus has the better initial presentation. But throughout 2022 that gap is due to close. Furthermore, I'm overall more forgiving of NASB because of the amount of passion that went into it, especially on the shoestring budget, so less bonus content is more understandable, especially given that Ludosity gets to keep working on the game and adding new content/polishing it. And finally, NASB is still fundementally a very good game! It simply needs more content and some extra polish (and this is coming fron someone who despises the elitism that came from Melee's happy accidents). And more of a personal thing, but Nickelodeon was my childhood while I have little to no connection to characters like Steven, Finn, Ruby Rose, Rock and Morty, Batman, etc.
A lot of the "anti-Multiversus" complaints come from people who are sick of it being called the "NASB Killer" and the obnoxiojs attitude that came with it.
Going back to NASB.
So, I've been revisiting the game's Loud House content after getting to know more of the show, and aside from the general apathy towards the show from the fans, the content in-game is generally a rollercoaster in terms of both passion and basis on the show.
First, the good! Lucy Loud (who they apparently had to fight for? Who would've gotten in instead?) has a very inspired moveset with a clear direction. There's a lot of references to things she does on the show, and while the coffin antics are a bit much it's willing suspension of disbelief for a fighting game, and isn't at all out of character. And while fighting her is a ****ing nightmare, you can see all of the heart that went into her moveset.
Alongside this, there's the stage of the titular house. Even before I started to like the show, I have to say I LOVE this stage. The show's arty style transitioning to 3D looks fantastic, the character cameos are great, the stage looks super detailed, and it's very fun to fight on. Feels like you're actually there! I know a lot of people hate walk-off stages but this stage is an absolute blast (and it feels a lot nicer than the typical themed platform a lot of more "typical" stages are. Irken Armada's a particularly egregious example, especially since Lylat Cruise showed us how to make a space fleet stage more interesting with a consistent platform). Only issues are a couple of minor inaccuracies regarding room placement and the type of fence at the yard's edge, but aside from that no complaints here!
Now we basically have the inverse, starting with Lincoln. Most characters have movesets heavily inspired by or based on canonical material. Lincoln....doesn't really have much of that. Based on what I've watched, only two moves seem to have been pulled directly from the source material (his Up Special (Ace Savvy) and Down Strong (VR Slash)). I can see him using a squirt gun, but I've seen people comment (fans of the show, in fact) that they have no idea where the Spinning Top move came from. Furthermore, no idea why Lincoln has a baseball bat since he tends to avoid sports (sans occasional games with Lynn Jr.). And I don't think he's associated with yoyos at all either. Based on his stage type, those last couple of moves, and being a small kid with a big head, among other properties, it feels more like they were trying to make a sort of Ness analogue rather than an inspired Lincoln fighter. I get that they probably had no choice in whether or not to include him, but it's a shame he didn't get nearly the same level of inspiration other fighters got, which are packed with canonical moves and references. (though I will say, his victory animation is SPOT ON)
Now, we have Lucy's stage, Royal Woods Cemetery. A big issue with this stage is that it doesn't do much to make itself stand out. If it weren't for Fangs' cameo on one of the dead trees it wouldn't even be particularly recognizable as a Loud House stage. It didn't go for the same "comic to 3D" art style that the House stage did, and is very light on the character cameos, too. If they had thrown in another character like, say, Haiku (Lucy's best friend) or maybe put an ARGGH! van at the mansion in the background, then that plus carrying over the Comic to 3D art style of the House's stage would've gone a long way! Standing out is important, especially that this game has an unusually high amount of spooky-themed stages (4 in a game with 21 stages).
You can tell that while there was loads of passion put into everything, some stages and characters got kinda shafted.
