Kid me played the SHIT out of this back in the day. When they first announced that guitar hero was coming to the DS I was extremely excited since I was a big guitar hero fan and had the proper DS to play the game on (sorry, DSi owners), and I'm pretty sure I got this game day 1. The songlist is pretty compressed due to the fact that it needs to fit inside a DS cartridge and the fretboard peripheral you stick in the gba cart slot is definitely not good for human wrists, but as a kid the game was everything I wanted; a way to play guitar hero anywhere, and even be able to play on the hardest difficulties due to the fact that the controls are more simplified this time around, with no orange fret and strumming being easier on the touch screen. This game really is a port that shouldn't have worked, but somehow they figured out how to do it right. If you have the means to play this, like guitar hero, and don't mind carpal tunnel, then give this game a shot
