rock band games lose value faster than madden games, if you have rock band 3 sell it and buy it back when you feel nostalgic a few months from now(if ever) for like $3-5. Or just get it on craigslist, activision whored that franchise to death so copies of the game are everywhere.
Nice try troll.
1. It's EA not Activision for Rock Band.
2. Rock Band 3's price has gone up since it's out of print and people still want it. It sells for $30 new, $25 used at Amazon and $25 used at Gamestop.
Unless you live in an area with a bunch of people selling games on CL, good luck getting a cheap RB 3 copy. I ended up buying it on GoD for $20 with some of my Target BF points.
