It is interesting to see that Tencent dwarfs everyone else, at least in the first two quarters of this year. But, I think that they have relatively less exposure to the west, where Q4 is generally massive. So, I'll be interested to see how this looks for the whole year.
I would also think that Apple and Google have relatively weak Q4s, as they're mostly in mobile gaming. I assume that mobile gaming isn't so holiday dependent (though I'm sure it is to some extent).
Hopefully someone will resurect this next year, when we can see all of 2018.
