Hey, I see you can buy it at Target. $99.99. Each additional pack costs 14.99. Definitely not worth it.
I also saw at the store today another Guitar Hero clone. You just plug the guitar directly into your TV and rock out to the 10 songs that you can play. Count it....10 whole songs! They don't even bother mentioning what they are, at least from what I saw on the package. Graphics looked horrid, and the guitar looked to be made of Tupperware.
I think we have the beginning of the tidal wave of clones.
