I think these diverse inputs are just a special case for Ryu.

Ryu's fighting game, Street FIghter, as well as many traditional fighters, feature complex button inputs to pull off sick combos.

The ability to do these complex inputs to pull off moves (and even get rewared for doing so) seems to be a homage to Street Fighter, and fans of SF as well.

Hopefully that is the case, because it could be a more interesting if more characters can do this

No.

Nope. It's what we, in the biz, call "a gimmick."

I hope so, I find SSB too basic. Id like it to have a combo system similar to ps all stars. Probably the only good thing about that game was the awesome combo system.

Yeah, in Smash 5 they'll be using this new system. Every character will also have a tome, a Levin Sword, Pikmin, a Luma, a Nana, a KO meter, three different movesets that change out when neutral B is pressed, the ability to absorb other players' moves, the Monado, Tippers, Counters, tether grabs, a motorcycle, a tree, a bowling ball, and 24 alternate costumes, 12 of which are designed to have Miiverse support to create the unique designs. Also it will be Mario Maker and launch on mobile phones in 2018.

I: toi awesome of post

It's just something special for Ryu.

Maybe, I m surprised how much depth ryu has though

It could be the next evolution of smash bros. If fans respond well to ryu's playstyle, it very well may be.
