In Japan, we think the most important aspects of this game is Combo and Tactics/Playing smart.
and we do not know which is more important. well, it does not have to be stated, they are both very important, and people think differently about this.
Here is a brief history of Japanese SSB scene.
Most Japanese players had been working on Tactics last 2-3 years or so, mainly because Redmario was on top of Japanese SSB64 scene even though he mains in low tier character, Mario. But Prince came into this and showed his beautiful combos, so a lot of players (even though they do not have much technique as Prince does) went for trying fancy combos which reduced their accuracy of combo.
So for a long period of time, many Japanese players (including me) were like
"I know tactics is very important but I wanna do fancy combo like Prince does."
If you play this game purely just for fun thats OK, but it is contradicted if you want to win.
and then Isai came to Japan, and killed us all pretty much.
We didn't understand why he was so devastating, but there was one thing we knew for sure.
If you get hit from Isai, you will be comboed to death pretty much.
so, we were reminded of the importance in the accuracy of combos.
(if you can make it fancy like Isai does thats great but its not essential)
Now, many players, like Tsukuru, started working on accuracy.
when I last played 4-stock match against him online,
he first did easy stable U-air falcon combo twice, which is very hard to DI out of especially in Japanese version.
I was now tired of doing DI. and the last two stock, he noticed that I was not gonna do DI anymore, and started trying some fancy combos.
I lost but I thought it was such a beautiful way of winning and applauded him.
He knows
what he is capable of
what he is not yet capable of
and what he wants to do.
