Yeah, it's used only, if you open a new game you're stuck with it pretty much, you may be able to get store credit some way or another but you'd be damn lucky to even get that.
Used though, it's np at all. I bought GT5 Prologue and Genji last Sunday. Beat everything in gt and genji is just fucking terrible, so I returned them both yesterday (Saturday) a bit before they closed.
You could basically "rent" whatever the hell you want for free anytime, but I would guess they keep track and would catch on... but then I dunno what they'd even do lol.
