Not to blame the victim here, but I don't know why people waited years to do this stuff...
I should've done it earlier. It's just that I had RB1 and 2 on PS3. Then RB3 on 360, and I did not really care much for the setlists enough to buy the other 2 games another time.
Then I stopped playing RB3, and I sold my 360 with anything Rock Band related because I did not think the franchise would ever be back. And now were are here. Lol.
Don't mind rebuying the RB3. It comes in useful soon now that its confirmed to be required for the export. At least I'm good as far as that game goes.
