It was. The original writer of Destiny's story was a huge souls fan. The Achlyophage Symbiote is a tribute to Solaire and his run in with the Sunlight Maggot.

Im not even talking about the cards, the stories in the gameplay, I could care less about the cards

So, gameplay story. What are the important characters in this gameplay story? What are you trying to accomplish? The characters are 100% lifeless. Zero interaction with them. At [b]most[/b] you bring them (insert quest item) so they can give you another mission. Does the speaker give you information? What makes you a guardian aside from the fact that you don't seem to be able to permanently die? (Neither do the enemies). At the end of the game, did you even make any kind of difference in the world? Nope. Patrolling the planets goes to show that your mission of pushing back the darkness has done nothing. The speaker says the same random crap when you check his vending machine that he did when you first got there. The gunsmith continues to sell garbage long after it became obsolete. It's like they took a game that had a story, and removed the story, and now you just have "game". If you think killing the "heart of darkness" meant you stopped the vex, or changed anything, you are mistaken.
