Ok, in guitar hero world tour you can customise your characters alot, paint their guitar, blabla and they have a song maker thats bairly usable, if your buying rockband your buying a music game not a paint guitar game. Rockband is a absolutly fantastic buy, for everyone, of any difficulty, we have bought some songs online, fairly cheep and all charted fantasticly, i advise the peace sells album by megadeth for metal heads, but theirs somthing here for everyone.rockband, all the way. Also rockbands presentation is much cleaner, sharper and pleasing. Last time i heard rockband and rockband 2 have somthing like 1000 songs on disk and on download, world tour have about 400. Iv also heard charting for gh metallica and gratest hits is poor and inacurate. for me this is your best buy.
