Why include a real guitar if you aren't going to get to play it like one?
As a guitarist, I find Power Gig: Rise of the Six String almost offensive. It had built my hopes up to hear that a true guitar would be included in a modern rhythm game. In my head, I imagined getting the opportunity to truly strum out some tracks, and learn to play some new songs in a manner I've never had the opportunity of doing. But no, rather than using the guitar like an actual guitar, players are stuck doing the same old Green, Red, Yellow, Blue, Orange button-based notes, with an occasional real power chord thrown in. Even worse, by now everyone is used to playing on a standard plastic guitar controller, making this feel like some unnatural compromise between playing that and playing the real thing.
