I had to point this out....great job Bungie! I would really like to see a lot more of these type of activities since you can use existing content and just add new objectives each week. On top of that, you can vary the objective difficulty and the type of rewards each week. It actually feels like an interesting/meaningful grind and would keep a lot of the solo players engaged. A huge chunk of your audience. EDIT : The Lost Prophecy Verses/Forge is also another noteworthy example. That really seemed to occupy us past the CoO campaign and milestones. #positivefeedback
