About 1 mth ago, i bought guitar hero world tour, then it also
has guitar, drum set & microphone.. there's actually not much
nice songs to play, but you can download songs created by other
gamers. you can also create songs by yourself. you can also design
your own character and instruments.
for me, i think that i will buy guitar hero, because there's
more type of games from guitar hero, like guitar hero 1, 2, 3,
aerosmith (dunno if got left out any). so at least the
guitar/instruments bought could be used for other guitar hero
games... for rock band, there's 1 & 2 only... but dunno about
future... haha
that's what i see for guitar hero world tour. for rock band, i'm
not sure as i never play before. anyway, i'm playing on xbox360.
