Are these the real Steam Workshop numbers?
ModOrNot stores public Steam Workshop counts from its collection runs. The totals shown here are the latest counts stored in our catalogue; changes over time are calculated from recorded observations, not invented values. They can differ from the live listing until the next collection.
