first of all some basic info which i think people appreciate but don't find in many reviews:
Game has 3 separate save files to save data.
Multi-card 2 player mode (Multi-card meaning each person needs a game cartridge and Fret board add-on)
Fret board includes a changeable cartridge pieces to allow it to fit into either DS or DS Lite (This is because GBA/DS add-on packs would normally stick out about 1cm on the DS Lite).
Strap, pick stylus, and stickers are also included.
Fret board has a changeable skin (more ways to make money I guess).
Fret Board consists of four fret buttons instead of the usual five.
The pick stylus is replaceable and can be bought from any good video game store.
Now onto my actual review:
The concept is great... Take the popular game franchise and make it portable. The game itself is not bad, the graphics are decent for the DS, and the strumming on the touch screen isn't too hard to get use to. you also have four buttons instead of the usual five which in theory should make the game easier and ideal to some players.
"Decent" and "reasonable" are the words that best suite this game as although the idea of taking the franchise portable is great for fans on the go, there really isn't anything new. You get a few features that only the DS can provide such as using the microphone to blow out a fire in duel mode but the game is let down by the difficulty in actually playing the game.
The problem in playing the game lies mainly in the plug-in fret board. For younger players this may not be a problem, but for teenagers and older, the Fret board can be very uncomfortable and painful just to play through a single song! I found it somewhat challenging to hold the fret board where i could both strum and see the screens, and remain comfortable. The frets are also a lot smaller than the original games, which is understandable, but in my opinion, just a little too small for most adult players. I also find the blue fret's position difficult to hit when you consider the length of the pinky compare to the rest of your fingers.
another thing that should be noted is that should you accidentally slide the fret board out of place, and disconnect it, you will need to turn the power off and on again. This can easily be done if not careful, but does not appear to be a problem if it happens when the DS is closed.
All in all you have a game which is fun to play if you can find a way to hold it comfortably, has decent graphics for the DS, and contains some good songs (some are from previous games though). One thing that is missing that i particularly miss is the artwork on the game screens fret board. This is however somewhat made up for by having your guitar of choice on the touch screen to strum.
It is entertaining and definitely worth a look, but at the end of the day, being able to take it wherever is just a gimmick and the game will never be better than the console versions. Get the game if portability is something that you would appreciate or perhaps if the console versions are too expensive, as in all fairness, this game and plug-in fret board package doesn't cost more than most other brand new DS games. But if you already have any of the games in the franchise, you're not missing out on much.
