[quote name='bmulligan']some import music game for the DS (which sounds very interesting)[/quote]
This is Daigasso Band Brothers. I wish I could listen to the CAGcast, but I'm on dialup.
I was just playing this game. If you at all like music games, enjoy DDR-type games, or have interest in musical scores or arrangements, this is a truly awesome game. Apologies if I am about to rehash what was in the CAGcast, but this is a great game that doesn't get the love it deserves. I love it as much as Ouendan, though in different ways. And that says a lot.
The closest thing I can compare it to is the homebrew PSP Revolution, which was essentially DDR using the PSP pad and buttons. But it was kind of limited and broken in a lot of ways.
Daigasso is like this, but much more interesting. You have to press buttons in time with the music to play notes. But each musical selection can have up to 8 different instruments, each with their own parts. You get to play everything in the song, from brass to strings to drums and it's all just like you would have in a real musical score.
Anyone who has played in a band or orchestra will immediately appreciate this. You don't have to be able to read music to play the game, but if you do, you get a bonus: completing Easy mode gets you a musical score editor, which lets you score 8 of your own tracks, with up to 8 parts per song.
This is a real editor, too. I still haven't figured out if there's a good way to look at all the parts at once (I don't think so) which makes it a little clunky, but it's a very impressive and powerful tool. It's not a toy. You could score all the music in the game with it and it's easy to use.
I can't say enough good things about it. Getting through Easy mode will take a long time, as there are a lot of songs, each of which have a lot of parts. Then you get Hard mode, with all new parts and a much more difficult set of button presses. There's a great selection of music, from J-Pop (including a couple of songs that will be familiar to Ouendan players) to classical to Nintendo songs, including Mario, Smash Brothers, and Fire Emblem.
