Its over in week. After that the only content you have left is to collect weapons and armors. Story will be over in probaply undr 6hrs. Strikes are over in few hours. Raid will take multiple hours in the first run. After that people are fastrunning it in under 1 hour. Roaming with new location its magical in the first time. After that i bet you are not even roaming. So there is your content. Destiny is not a good RPG, because it lacks with content. True MMORPG games have 4x more content with their 20$ expansions than TTK can give you with 40$.
