I used to really like this game. The gunplay and art direction are spectacular, although I got bored of the enemies. I stopped playing a while before they deleted whole planets and questlines, and haven't felt an urge to go back. Shame, because nothing else quite scratches that itch.
Yeah I bought the original destiny collectors edition, with the little ghost collectible toy thing and all that. I never even bothered playing the second game.
The latest expansion genuinely did shake up the enemies. They still need to ... change something. It seems like maybe they will with the next expansion changing how they present the story. We shall see.
