Your as much a personality as Soriku.

 Take that as you will =P
 

 Those games aren't true 3-D.  They are 2-D with a Step.

You could do it easy if you had a "lock" button to switch between opponents.  Still wouldn't be as fun. 

Lock on button.. Hmmm....What does that remind me of???

Oh ya!

PSP Shooters!

Talk about taking the fun out of a game...

No, Just no, never, absolutly not....... lol nah like Rol said 3D view with 4 people will be incredibley hard to pull off and still have decent game... not impossible but hard.

I don't think Tekken, VG, or Soul Calibur are in 3d, persay.

They are generic 3d, as in, they give the illusion of being in 3d, with sidestep and plane changing maneuvers.

However, until you can literally turn your character around and run diagonally away from your opponent, it's not really a full 3D experience.

There was a brawler for Dreamcast, you guys remember that game? It had full 3d and destructable stages. That game was pretty decent, so a decent fighter can be made in full 3d, and it'll be more like Final Fight, Double Dragon, or God Hand, if that's the case.

However, 2d goes with the nature of smash brothers, and changing it would make it a whole different game, which is bad, because we love it how it is.

Oh I do think it'd suck compared to 2P ones.  Though that is how it would work.

Custom Robo wasn't bad with the lock on switch in 2 on 2 matches.

@Zenfolder: You're talking about Power Stone, which has already been mentioned.

i think 3D would be very hard to implement successfully so i don't think it could exist.
