I got this in gamestop's PS3 bundle on black friday, still wrapped and everything... Apparently it's got 30 dollars worth of dlc in it as well.
I used to have LBP back when I had my old PS3 and I've played it so much back in the day that I just don't feel like keeping it around anymore.
I will trade it for a new PS3 game... it doesn't have to be wrapped or anything, as long as the disc is scratch-free (as if ps3 games get scratches..) and have it come with the box and manual. As long as it's in mint shape and looks new I'll go for it.
Uncharted 2, Assassin's Creed 2, or Modern Warfare 2 will do. Send me a PM if you're interested.
