Several FPSs arguably just as good as Halo have come along since its debut, but its the public's familiarity with the franchise and snowballing word of mouth that has primarily made it excel where its peers can't. I feel the same will hold true for Guitar hero. Rock Star will seem neat and many will love the idea, it will probably even be a much much better game, but the practicality of all those instruments and having the people to play them all to fully experience the game alone will make it intimidating and limit its sales, Guitar Hero, as the already familiar franchise of choice by that virtue alone will have the advantage.
