I've now realised that my gaming days are truly over. As a last foray I bought Far Cry 3 and GTA V.
Far Cry 3 I couldn't even bother with after the first mission.
GTA V I managed to finish, but it has no replayability value to me.

So what do you do with PC games these days after you're done with them? Chuck them? Gift them / Sell them? Will they even work for someone else, or are they associated with my Uplay / Rockstar accounts?
