[quote name='CombatCraig']I'd get Guitar Hero III but I have a feeling most of the songs I'll want will be on this Greatest Hits thing coming out, plus I'll be able to play them on all of the instruments instead of just guitar.
But thanks for the heads up OP[/quote]
Yes, but you are also talking about $12 vs. $60. FYI, the "greatest hits" disc is a standalone. You won't be able to integrate them with the World Tour songs and DLC.
