Ordered from game last week, came today, day before release (woohoo!)
And I'm only off it cos my fingers are killin me lol.
It really is good. I've got all the guitar hero's on the 360, having a mobile one is soooooooooo good, though, i havent gone out yet, i've been playing it hehe.
The addon fits great, and it all works as it should, have to use headphones though cos of the DS's poor speakers.. doh, Will be the only Game i carry, my cycloDS is the best thing since sliced bread, though i may have to port my savegame from the actual game and put it on there when the english rom comes out..
