I've been out of the loop for soooo long now, just picked up a PS4 with the intention of staying in more with the girlfriend so we can save money (she loves gaming), will probs be on the lookout for a used one too for her as there don't seem to be many (or any) decent 2 player co-ops unless they are online.
One game I have been itching to get is South Park, can pick it up for under £15 used but I remember reading somewhere that ways the developers were trying to keep up retail sales was to offer DLC content that is only valid for the original purchaser, so any pre-owned games are only half a game essentially. Is this the case? Are there any sites to see what you lose by going pre-owned on any games? Because I'm so late to the current gen consoles there must be a huge back catalog of awesome games that I can pick up for next to nothing now!
