So a friend of mine copped a Nintendo 3DS with SSF43D. I played it for a bit and I can tell why people are calling this the best launch title, even though its a port of a game that's been out for about a year now.
The game is beautiful, 3D mode for Street Fighter is awesome. There's actually two ways to view the fights; in normal mode, which is the standard way to view fighting games, and in dynamic mode, which turns the camera to a behind the fighter type of angle that's literally kind of like what you seen in the commercials (if you've seen theme). Chun Li fans, rejoice, she looks amazing in Dynamic mode.
Still, this is not a game for serious competition at all... you might as well play it on the consoles if that's what you're going for. The d-pad works fine, I guess, and you're definitely going back to the SNES setup when it comes to mapping your buttons and whatnot. But the easy mode buttons? That changes everything, and is essentially the reason why the game can't be taken seriously in my opinion.
I had read an article about how this is the first step of how Ono, the producer of Street Fighter, wants to reduce fighting games to a casualized attack fest (well, that's not what he said exactly, but that's clearly what he implied). Talk about a first step... anything you ever seen anyone ever do in this game, you can probably do it. If you're Sagat, you can set a button for EX Tiger Uppercut, set a button for a Focus Attack, and set up a button for the Ultra. Then you can do the combo with no problem... all you gotta do is know how to dash.
Don't even get me started on Guile... Sonic Boom and Flash Kick without having to charge?
All in all, it's a fun experience, which is what I guess they were going for. But it's seriously too easy to take seriously... so simply put, your ability to enjoy this game will be in your ability to not care about being competitive.
And remember, according to Ono, this is the future of fighting games..........
