This is probably gonna be a big one, let's see what I can think of:
Fighters
-I think of echoes as whole characters, and will have them separated in my roster. I'm sad it looks like echoes will be in the slot to the right of their original character, if you're gonna let people separate the echoes, at least put them in release order.
-I'm gonna miss
's Gale Boomerang on a strategic level, but I'm glad they're lining him up more with his BotW incarnation.
-
and
's realistic animal sounds don't bother me at all. However, I'm worried they won't keep up the consistency and end up making K. Rool sound less realistic.
-
is objectively the best fighter in the franchise and the fact that this opinion is unpopular sickens me.
-Really wish
had Majora's Mask-related items...
-Alph desperately needs to be an echo with Rock Pikmin.
-We really don't need Isabelle, echo or unique.
represents AC
perfectly.
-I like
's move set aside from the Down B (which may be better now that it's faster), it was weird to get used to but once I did, I liked it.
-I
love that
exists. I mean, I never use her, but still.
-Miis (where are the icons?) should be playable online. A fighter is even a fighter or they're not, don't make awkward compromises.
-
's move set is great.
-Not sure how unpopular this actually is but the PAL name "Duck Hunt Duo" is stupid. There are 3 members of the "team", and the "team" is called Duck Hunt.
-I felt from the very beginning that
did not belong in Smash, and I still believe that now.
fits for some reason - hell, maybe it's just nostalgia - but Bayonetta just felt like the first mistake in the franchise for me.
-
is too big. The down-scaling has made him look
reallllly awkward.
-
was the last newcomer I wanted in Smash, anything from now on is just icing in the cake.
Though I have since started really holding out for Skull Kid.
-I wouldn't mind not getting a new Pokemon rep. However, I think we almost definitely will get one. Super Smash Bros. is a great advertisement and Gamefreak could definitely do with some. I do wonder though - considering that the new games are based on Gen 1, rather than the newer Pokemon - if we'll be waiting till DLC so we can get a Gen 8 rep.
Stages
-Sorry, for me the game isn't ultimate until every stage is in (except Miiverse IMO, which is more of a gimmick than a stage). It sounds really selfish but it's just the way I view it.
-I'm worried that constant blue stream in the background of FD will be distracting. I mean, I don't play competitively so it won't bother me personally, but I do wonder.
-N64 stages really should have been re-created, maybe with an option to play the original versions as a skin.
-W-why isn't Pictochat 1 back? And why hasn't it been combined to create Pictochat X?
-Nitpick, but on the same topic... Flat Zone X should be re-named Flat Zone. Having the "X" will be a tad confusing for people who are just starting out with Ultimate, or who aren't as obsessed with Smash as we are. As a kid, the console names before retro tracks in Mario Kart Wii always confused me.
-RE-NAME "MUSHROOM KINGDOM II" SUBCON!!!
-Really worried the team's gonna forget about Mushroomy Kingdom 1-2, we've seen no sign of it thus far.
-Same as above for the B&W version of Dream Land GB.
-Same again for the daytime version of Wily Castle.
-Mushroomy Kingdom's aesthetic has never bothered me. In fact I like it, it's a really interesting concept, seeing the first level of SMB over 30 years in the future.
-I'm just now noticing this - and it's another nitpick - but Smashville feels like it's lost the Wild World aesthetic with the rigid edges and polygonal background characters being changed.
-Pac-Maze is possible in Ultimate with some tweaking. Just make it so only one player can use a power pellet at a time. It's not like stages are immune to tweaking, Gaur Plain was heavily changed between 3DS and Wii U.
-It looks to me like there will now be a Mii in every room of Tomodachi Life. I liked the fact that only 3 of the 6 rooms were occupied in 3DS because it's truer to the source game, where Miis are constantly leaving their rooms to go take part in activities across the island.
-Stage Morph is neat, but a gimmick like that really shouldn't limit a stage from getting into the game (Jungle Hijinxs, likely).
-New Donk City Hall only focusing on the City Hall rather than the entire Kingdom doesn't bother me purely because the actual Kingdom itself in Odyssey didn't have any particularly interesting attractions, unlike Delfino Plaza.
Misc.
-I'd love a boss rush. A story mode would be great but I think that's heavily unlikely. A fun boss rush through different franchise's iconic villains would be great fun!
Whew... that's all I can think of for now, and probably more than my fingers can take. I'll add more as I think of 'em!
