TPG says, "The first thing to realize when you play Rock Band Unplugged is that you must leave your biases at the door – this game isn't attempting to 'simulate' playing a musical instrument at all, and makes no effort to feel like it. This is a game that has set out to approximate the Rock Band experience on your PSP, and the victim in this conversion was any feeling of playing a musical instrument. This is especially apparent when playing the singing parts – there's just absolutely no connection between what you're playing and what is supposed to be happening. I think it would have worked better if for some songs, you had the option to play rhythm guitar or electronics parts instead of the vocals, as this would've felt a lot better than playing vocals. My suggestion is to get over this and to just enjoy the game for what it is instead of what you expect it to be."
