Destiny Vanilla all the way through to TTK was supposed to be in the original game. There's videos and screenshots of e3 gameplay in 2013 which is like pre alpha. There's a section where guardians are fighting an ogre on the dreadnaught, there's also another scene where a guardian flies in to earth from orbit and you can see they had 'The Waning Star' which is the taken ship. Rise of iron was the only dlc that was created after the original game shipped. All the others were cut up and set as "DLC" because Joe staten left before destiny released.
