The most interesting part is the comparison to New World which is only available through Steam and doesn't have its own launcher like Neverwinter or STO. So if you combine the Arc Launcher numbers (which are likely higher that the Steam numbers) with the Steam numbers, the population for Neverwinter and STO are probably not that much lower than New World, which also has a much bigger budget and team behind it.
