I want to buy this for a gift but see that the GOTY has some extra features like "Play as Joker" and 4 extra missions. If I buy this USED, does this mean that someone used DLC codes to get that extra stuff and I won't have it on a used version. OR is it just something you can download from PSN for free? And do you HAVE TO HAVE the GOTY version to get the extra stuff? What if you have a used version of the very first black release?
Sorry for the long question, but I'm just trying to understand this so my nephew won't be disappointed for his birthday?
