Can someone talk me through these? DH asked for Guitar Hero World Tour for Christmas. Not a problem, though I'm not nuts about the songs for my kids (who'll want to play.) Band Hero and/or Lego Rock Band look to have more, er, family friendly lyrics... Can I get the GH bundle and then the separate Band Hero or Lego games? (or would Lego not work with the instruments, because it's RB, not GH?) My other option is just getting the Band Hero bundle, though I note that just jumped up $30 from the time I started looking yesterday. Ugh! What am I missing that the Band Hero bundle is $200, but the World Tour bundle is $120, the Band Hero game $50, so together they'd still be less than the Band Hero bundle?
