The difference is that they get what is advertised. Here we have an "expansion" that doesn't expand much. Yes, a few new missions (one of which cannot be replayed for some reason), two strikes (if you use PS), and a raid. Should we be able to finish all of the "expansion" in one day? I myself have not finished everything, I don't have the time to complete everything at once. Still, if I had one day dedicated to the PS4, I could do it. They should have just called it DLC instead of calling it an expansion, people thought they would be exploring new worlds, fighting new enemies, and getting new insight into this story that we so badly want to know. What we actually got was the same locations backwards with higher level enemies. Sure it's more to do, but I think it's fair to say we all expected more. Just to add one thing, I enjoy playing the game and have invested many, many hours into this game.
