I honestly think that Sony does that with most of its promotional copies of games. Before I joined On.PlayStation, I used to receive free games monthly from House Party. I don't knew if anyone here was apart of it, but you posted on the forums, uploaded photos, comment on other posts and you works get free swag the following month. You'd get two to three games each month. Too bad it's not around anymore.

Anyways, they used to slash the bar codes as well. It didn't matter to me because I kept almost all of the games. (Sorry for that trip down memory lane. Lol)
