I don't think there's any need for a new type of move. Right now, the game has a really nice sweetspot where it's simple enough to pick up, but doesn't sacrifice depth for it either, and there's still a lot of room to be expressive in how you play. For Smash 5, the best route is fleshing out each individual character.
edit: fixed redundancy in phrasing here
I very much agree with the points that
Verde Coeden Scalesworth
has been making regarding WFT.
Wii Fit Trainer's appeal has a couple of aspects to it:
1) "it'd be really funny if she were in Smash"
2) "Wii Fit was a hit and is iconic in its own right"
- (appeal for the
character, and its representation)
3) "it's easy to implement all of these yoga poses as attacks, and it'd also be a unique set of attacks"
- (appeal for the
gameplay, and the moveset)
Isabelle has her popularity going for her, so as a character, her inclusion has a lot of merit – which is why she appears in, for example, Mario Kart 8. In a fighting game environment, though, if she doesn't have the gameplay viability to back that up (e.g. if it would be out of character for her to beat somebody up), then that hurts her a lot. As we've seen with Ridley, Sakurai is a big proponent of "do it right or don't do it at all" when it comes to properly representing characters, and he takes it quite seriously.
As far as why "accidental fighting" is forced imo (to respond to
MamaLuigi123456
), these are the main couple reasons off the top of my head, which I also noted in my RTC posts:
- Dissonance between the player and the character, i.e. I want to beat up the opponent but Isabelle doesn't
- It paints her as quite an idiot: if she doesn't want to hurt people, then you'd think she'd stop dropping books on them
- The best logical implication from such a moveset is that she's some sort of demented serial killer who DOES want to kill the foe, but is trying to cover it up by looking clumsy (which I'm not sure is the best way to paint Isabelle)
As I stressed in RTC, my stance here is very much based on how she's purportedly a pacifist. I've never played the games myself, so I don't know what would or wouldn't be out-of-character for her. Based on what others have been saying – including direct statements of "she's a pacifist" as well as it apparently being necessary for her to fight by accidentally hurting people – I'm led to believe that directly fighting
would be against her character. If that's accurate, then I don't like the sound of her in Smash. If I'm misinformed about her personality, then I've got nothing much against her aside from not jumping out at me with moveset potential.
Here's hoping! I did make a
Smash 4 mod of it a while back, it'd be awesome to see something like it as an official stage in the Switch version. I wonder whether they'd use a more traditional style, or base it off of Odyssey's version. Maybe even World Bowser or something, given Smash often pulls from the previous console generation for its Mario stages?
