Super Street Fighter IV is looking quite good on Nintendo's 3DS. Let's watch some gameplay, solo and multiplayer.

At the Nintendo World 2011 event in Tokyko this past weekend, Street Fighter producer Yoshinori Ono presented a live demonstration of Super Street Fighter IV 3D Edition, a 35-character fighting game based on last year's hit, scheduled for Nintendo's new 3DS portable system.

We've seen trailers, but now we can see it being played.

The Capcom folks play some Super Street Fighter IV 3DS solo:

(These videos are captured from Nintendo's live stream of the demonstration. The stream, which you can watch in full, surely doesn't show the graphics in the quality they appear in real life. Still, they're quite good.)

We're just seeing the 3DS' screens in this video, so we can't see all of the button and stick commands. The 3DS has an analog-slider and thumbstick d-pad on the left and face buttons on the right as well as a pair of shoulder buttons. Whatever manner with which those are being used, the system also evidently uses the 3DS' lower screen, the touch screen, for special moves.

The game was shown in 2D, but the 3DS' top screen can display the gameplay you see here in 3D, glasses-free.

Later in the event, we got a look at multiplayer.

And we'll wrap up with the latest trailer, which isn't that different from the one we saw in September. Clearly, the focus for this version of the game is on the many different ways to play the game against other people: in person, online, passively, actively and so on.

The 3DS will be out in Japan in February and in the U.S. in March. Super Street Fighter IV: 3D Edition hits Japan on the system's launch day, February 26.
