Rare Replay

In Rare Replay you are given player ranks for how many milestones, snapshots and snapshot playlists that you complete. These are represented by stamps that go onto your player rank. It takes 6 stamps in order to go up a rank and you will have to go through Spectator to Spectator V which will take 30 stamps to get to the player rank of Follower. The achievement will unlock once you get stamp 30.

You can get 21 stamps by just playing all of the games that are already on the Rare Replay game (without having to exit for an Xbox 360 game) and then by doing snapshots of any game or by playing through the games to complete milestones which you will have to do for the other achievements in this game.
