At the moment, when you buy your copy of Rock Band for $170, you get one microphone, one guitar, and one set of drums-enough instruments for three people to play. The issue is that the game is designed for four people and, as we pointed out when gave the game our game of the year nod, that's the only way to really dig into what the game has to offer. There is no way to buy a second guitar at retail, and only the 360 version allows the use of Guitar Hero controllers. So I wondered, how are people getting their second guitar?
