When I rented Guitar Hero, it was pretty fun. It has classic hits you could play, with awesome sound quality.
The guitar itself is light and easy to handle, anyone could reach the 'strings' and play. There is a easy, medium and hard level. I would recommend that non-guitar musicians stick to easy and medium. Hard is very challenging and fast. Some of the loading moments are a little slow. From my experience the cd is easily damaged(not physically) for some reason or another. For example, my friend had just bought his Guitar Hero and played it twice, then it started continuously freezing or just not loading at all, we checked for scratches, but is was clear of any marks and still brand new. We gave it a clean, but we just couldn't figure out the problem. So be careful with the cds. The game is really fun overall and will make u feel like an awesome guitarist.
