Removing the guitar peripheral – which is what made the series famous – is an odd, if not questionable step. But in the interest of system portability, it’s understandable why it had to be done. Instead of a plastic toy guitar, we have an add-on to the DS that plugs into the GBA game slot. We now have an emulation of an emulation of a guitar."
