I bought a used copy of destiny at a second hand store here in my hometown, I'm really confused because the gameplay as far as I can tell is the original destiny. But at the start menu and on my ps4 menu before entering the game. It says, the taken King. Which obviously is the newer one. So any reason why it may be doing that? Also if it helps at all when I put it in the ps4 the first time it had a 2 hour software download.
