Since a vast majority of our community moved over from the PS3 to the PS4, they had to leave GTA V behind. Not many others want to spend $60 on a game they've already beat either.
I love R* but the fact that they promised heists for such a long time and now (what 2 years later?) it's finally here just leaves a sour taste in my mouth. Now, I might hop on and try them... but I don't really care about it anymore.
