I got Guitar Hero World Tour (PS3) ages ago and now I want to get into RB. I'm looking for tips for the most cost effective way to do this.
AFAIK, I should look for a used copy of RB1, and I need a new copy of RB2 and Lego Rock Band for the export keys.
Do I need a new version of RB3 to import to, or can I get a used copy of that?
Any other money saving tips?
