Anecdata, friend. Two old friends became extraordinarily good at guitar hero and even won competitions. They're also some of the best guitar players I know. One of them is an extremely good drummer and can do improv piano like a beast. They'd both agree that guitar hero helped them play better. What are your thoughts on games like Keyboard Hero?
