"In the end I obviously would recommend the game, but with the caveat that unless you are absolutely dying to play it right now it can in fact wait, as Rock Band is a known quantity. There's nothing very drastic here unless you're a total freak for the drums, in which case there are no reservations. If you are invested in Guitar Hero as well you'll be happy to know that the instruments supposedly play nice between GH:WT and the RB games. Take a look at the tracklists for each game and decide accordingly. It is all about the content, after all."
