This isn't really a big argument as Ultimate had like 3 brand new stages, bringing back old content took up a lot of resources too so there wasn't much priority at all
Yeah I wouldn't consider it a big deal either, but the lack of SwSh content when they knew it'd be releasing about month before this was a bit surprising. I mean, they could have easily just asked the Pokemon team for a couple of music tracks or a model or two to use for a Pokeball pokemon.
I mean, pokemon does have a lot of content, so I can't really complain that much, but....I miss Pokefloats.
Also, on a slightly unrelated note, though I like the designs for most of these DLC stages, I'm a little disappointed that there's no real stage hazards for many of them.
-Mementos has the shifting blast zone walls and a subway train running through the bottom of the level, so it's awesome in my opinion, but the rest are lacking
-Hero's Yggdrasil stage only gets a Mimic if you've got items on; otherwise its just floating with the occasional island platform appearing & disappearing.
-Banjo's just rotates and that's it
-Terry's, while a cool concept with the fighting stage-style walls, was just an arena with Fatal Fury cameos; no hazards
-Gareg Mach stage was just a showcase of, well, Gareg Mach. It moved from area to area within the monastery with some destructible environments, but thats it...no hazards
-Min Min had some platforms that superpowered your jump and narrow ceiling spots, but that's it
-Steve's was basically just a 8bit version of mario Maker with slightly randomized level design each time
-Sephiroth's was just Final Destination with FF7's ending going on in the background; spoilers be damned
-Pythra was again just a battlefield-type stage where one side's ledge occasionally, slowly, turned so you couldn't hang from it briefly
Where are the more fun stages with random stuff that can happen like Pokemon stadium's shifting type arenas with effects going on? Or Rainbow Cruise where it's a side-scrolling level that requires a bit of platforming as you jump & fight? Or Legend of Zelda's boat that can be beached or fired upon by canons and such?
Come on, get creative! Give me a character who comes with a level that isn't just Battlefield or Final Destination reskinned or floating through the source material's environment!
