That’s a rather petulant take though.
I mean, the API provides the equivalent of walking up to the WoW house, knocking on the door and having Mr. Blizzard open up, and then go:
“Hey there Mr. Blizzard, could you tell me roughly how many people are inside the WoW house?”
“No. Go away.”
“Okay, bye!”
…And then proceeding to go over to the nearest window and look inside and start counting.
I mean, that’s what the APIs allow for – a window to look though, giving us a means to count.
Maybe the data we collect is off by a bit here and there because something’s hiding in the corner, but for the purposes we’re using it, it’s accurate enough.
Like, if we conclude through the API that 500.000 people have played The War Within (outside of China), then even with a margin of error of 50%(!) that would still only amount to a maximum of 750.000 people. So we’re still in the same ballpark.
And that’s really as accurate as we need it to be. Is the game played by thousands, a million, or many millions?
