I play League still, although it's been harder to commit to a potential 45m+ game with no pauses. Atlas Reactor has been fun. Tactical RPG meets MOBA, recently went f2p. Other than that, it's been Human Simulator 2017.
The only objective that feels *vital* to me is the NPC, if it's working like the help file indicates. That's why I suggested the refined timezone vulnerabilities a la Citadels. As an example, the NPC could get 4 hours of vulnerability a day, the standard 8, and the statue 12. Double those for stolen objectives. Unlike outpost design, that doesn't just make you off-hours another objective (or 5) to achieve your intended one.
