While Super Street Fighter IV 3D Edition is one of the best (and most elegant) multiplayer games to ever appear on a Nintendo platform, it's worth remembering that this is, at its heart, the second update of a two year old game. That means the graphics aren't as impressive as you might expect from a launch title for a system whose main selling point is its graphical differences. In 3D mode especially, the backgrounds appear incredibly static -- almost cardboard-like.
At its core, though, the game remains a good fighter. The action moves quickly, and there is a tremendous variety of moves among the large collection of characters. Finding a random online opponent is easy (though the matchmaking service isn't fully up to snuff yet), as is connecting with friends. Fighting in the system's 3D mode takes some getting used to, but it's a nice (though unnecessary) addition, letting the characters stand out as they battle. Longtime fans of the series don't need to buy yet another version, but for new 3DS owners looking for a quality game for older teens, this isn't a bad choice.
Online interaction: The game will let you play with strangers over the Internet, but no personal information is exchanged and there is no voice chat. Similarly, you can play against someone close via local wireless. And the system's StreetPass mode lets your system compete with other players on its own. Again, no personal information is exchanged.
