Ace Gamez writes: "Ah, the humble DS Slot 2. Once a praised effort in providing backwards compatibility for those faithfully upgrading from the Game Boy Advance, it succumbed to Nintendo's curse that inflicts an unpleasant flaw with every incarnation of its handheld devices. The GBA required the light of a thousand suns to see anything happening onscreen, the SP lacked the all-important headphone port and the first DS was as ugly as a bulldog licking wee off a nettle. The DS Lite was no different and if you've ever tried to play an Advance cart in this console then you know what I'm talking about; the half-inch protrusion that ruins the clean lines of an otherwise beautiful console and feels so very flimsy and unsafe. Well, now Slot 2 has something to be proud of in the form of the innovative Guitar Hero: On Tour Guitar Grip.
Whilst guitar-based music games aren't new in the gaming world anymore, this is the first edition to hit the handheld market and Red Octane seem to have found a niche with the DS and its highly adaptable touch-screen interface. What we need to determine, however, is whether or not the highly successful Guitar Hero series can cope with being scaled down after we have seen the benefits that DVD and Blu-Ray can provide in terms of sound and video quality, as well as a staggering number of songs (with more regularly becoming available through downloadable content) that can be stored on a hard drive. If these issues are covered with style and grace then the appeal of portable rockin' is easy to see. Why be staring out of the car window, wishing you were somewhere else, when you can be on stage in front of thousands of adoring fans, screaming in delight as you pluck out historic melodies and thrash your way through the ages of rock?"
