Some sort of interview, I dunno, and it has a few little tidbits of stuff to come for Melee and could/did help for Brawl/SSB4, the most interesting stuff being from Middle to Bottom, but the Top may be useful to some.
It explains pretty cool stuff like how Wario was going to be a Slower, Heavier Mario/Luigi, how every Mario Character (Mario, Luigi, Peach, Bowser and Wario) were going to have the "Mario Tornado" Down B, how Popeye maybe was going to be in Melee and alot more. Check it out.
(Also, Mars = Marth, most of this isn't translated correctly.)

I'm not sure this kind of thing is allowed on the character thread. @Hong is this a valid thread?

I think the thread is alright, but I moved it to the SSB4 WiiU Boards.

Neat read. Bit random, but like you said, doesn't hurt to take the time.

From what I understand, these are user comments and speculations.

(Also, "Pudding" is a direct translation of "Purin" [Jigglypuff].)

This is just a bunch of fans saying what they like about smash bros, the creative ways they play the game (Giant Mario bros only/ Baseball with Ness/ etc) and what kinds of moves they want the characters to have.
Its like japanese smashboards.

Can ya put this link to the original webpage in the first post.

There's over 100 pages of comments...

One post stood out to me

"By the way, I do not have plans to make continued thing of Joy Mech Fight?
I have been doing Joimeka NES sometimes even now.
No ~ ~ Neo It is strong. Kana also star?"

I'm guessing this translates to

"By the way, do you have any plans to continue the Joy Mech Fight series?
I still play Joy Mech Fight on my NES* to this day.
But if you don't have any plans to make a new Joy Mech Fight, can a character from the game star in Smash Bros?"

*Isn't Joy Mech Fight exclusive to the Famicom? Did google translate Famicom as NES?
