Was expecting this...
Let me try:
As much as I've been finding most of these newcomers ones I've been acquainted with before in some form or another, I would have rather wanted to see Dixie, Toad, K.Rool, Ridley, Isaac, Takamaru, Lip, Mewtwo, Roy, Tingle... you know, all the folks we all speculated on majorly, and as of now only three (Little Mac, Palutena and Mega Man, I guess Shulk + Chrom) got to be in. Rest are up in arms with controversities through defending Sakurai's genius, dealing with losses and tolerating/jumping to the support because well, they made through the cut. Never the less, I might keep on feeling there could have been more characters the fanbase would have loved as much as the newcomers Sakurai putted on creativity about. Or heck, even more than what we're getting.
Frankly, I keep thinking that SSB-series is about to lose what sparked my love for it a the first place: the playground for match-testing and putting my beloved Nintendo-characters take on each other, as well as an amazing gathering of them all together. Particularly those who I'm familiar with and been acquainted with before SSB, and after SSB because I found them cool in their original games, and are well-established representatives of those franchises. (For example. the Core 4s, like SMB's Mario, Luigi, Peach and Toad, DKC's DK, Diddy, Dixie and Cranky Kong. Or KDL's Kirby, Meta-Knight, King Dedede and now Bandana Dee. )
Likewise, Pokemon's most beloved, Pikachu, Charizard, Mewtwo, Lucario, etc. Also the two significant characters from some series, like Samus and Ridley. You get me?) And then the characters out there that you've never seen before, but have history that's well-hidden, but that seems kinda covered in this installment (Shulk? Little Mac? I dunno.)
What I don't like now is that at the moment, it's about whoever is chosen as a fighter for certain reasons or just merely because Sakurai felt interested on being creative with them. Like, who wanted Wii Fit Trainer? Are we forced to like her now or respect more than some characters we were acquainted with in the past from our childhood because Sakurai made her a fighter?) and gets to bask in the beautiful spotlight of recognition, usually new-found popularity, and "tears of fanboys" because they took away another opportunity for more fun and relatable match-up or gathering of characters you wanted to take on each other but only could do so in Smash Bros (such as K.Rool VS Bowser, Toad VS Bowser Jr. or Bandana Dee, Ridley VS Mewtwo, etc.). All while Sakurai's crowned as an eternal genius for just the characters he's including, no matter how absurd, and ABUNDANT, they can get.
Lastly, those who're left in the sidelines are always gonna stay inferior to the ones playable, to the point that they feel waste of breath and code in the game because they don't hold any significance to the fanbase community except bitter feels or plain uninterest. They're nothing more worth than a mere virtual dog or angry mole yapping at you for 3 minutes straight. But that's charm of Smash Bros for you. They're nothing mere than pseudo-summons that are forced to help you rather than help you because you want them to. There's no way you can touch on them with as much beloved affinity as with playable characters because frankly, they're tools with A.I that resemble their more remembered selves from the games they're from, usually with as sweet, or even sweeter memories than some of the fighters in the roster you see.
I might sound self-entitled, but I at least told my reasoning for why I feel all this.
(And I'll never be able to relate at so-cloney "Toon Link" with as much fondness as I have at "Hero of Winds" from my childhood. Ever. )
