Capacity

Across all three games the network advertises 3,884,191 player slots and is currently holding 193,311 people. Slot counts are chosen by operators, not earned, so the gap between the two is worth looking at directly, the figures below follow whichever game you select.

Fill rates use each server's highest observed population, not its current one, judging a server by its quietest hour would call the whole network empty. The axis on the chart tops out well under 10%: no size band comes close to filling what it claims.
