I like the idea that you get many exotics with quests and not every quest give you an exotic (example: Black Spindle in contrast to the Paradox mission). It is really fun. But the execution on the Sleeper Simulant was sub par. It didnt live up to its hype. Dont get me wrong, the weapon is pretty sweet (although the feeling of the weapon isnt the best). But the quest could have been better. The mission had no voice acting and no explanation. I was excited to go on this adventure but at the same time i was like "Why am i doing this? How does this fit in the world?". The second flaw are the codes. Where in the world is a connection between the way Knights spawn and a device obviously not made by either of these. Had Rasputin called them? I see no connection and its a purely mechancal reason. Its somewhat lazy riddle design. And the third and final flaw is the length of the mission. Compare it to the sword quests. The sword quests takes you some time to complete (partly because you have to wait for armsday). After i completed it i felt like i had accomplished something. The Sleeper Simulant quest was over before it really started. At least that is the way i felt it. I think a big reason for the disappointment is that the Sleepers Simulant was way overhyped. Partly because of the Gaminformer article and partly because the community was way too excited. So in conclusion: The quest didnt live up to its hype and the riddle was way too disconnected from the world. Please bungie make more riddles like this. But please make make them part of the world. And please please please never make a mission without voiceacting. You did a great job with TTK with a good storytelling and you kind of took 2 steps back with the first Sleepers Simulant mission. TL:DR: Good Idea with the quesst, lacks in execution
