| Well I don't own rock band, but I wouldn't suggest buying it if you're the type of guy who chills at other people's houses who own it(such as myself). Sure it's cool to do the vocals and drums, but if four people aren't going to play it frequently I don't think it's really worth the money. Otherwise, if your house is a hot spot for friends to hang out or you have family that enjoy guitar hero then I would say the buy is worth it.
Edit: Ehh, that doesn't really answer the question does it? That refers to buying all the instruments. |
