Should I get Guitar Hero: Metallica?

Basically, I'm dieing to buy Guitar Hero: Metallica as I love the guitar hero games and Metallica are one of my all time favourite bands.
However, I only only a guitar hero guitar, not the drums, microphone or bass.

Do you think I'd still get good value for my money still?

Thanks

Get it, you will be pleased.

As long as you have a guitar, you'll enjoy the game. You can ALWAYS get the other instruments later.
