These are placeholder for the time being and certainly raise a few legal questions, which is perhaps a key reason they will be phased out, but they add some familiarity for returning players while looking nicer than the dated Guitar Hero 3 visuals. Unlimited song numbers, incredibly quick load times, cleaner UI and backgrounds, it had all the basics that a good, modern, Guitar Hero game needed.It also has art assets taken directly from Guitar Hero. But Clone Hero offered so much more, even in its early stages.
