It cannot be 55 because, for example, some of the largest ecosystem + making multiple times profits only have folks around that level.
That's not really true. The PC market is massive and worldwide.
There are digital distribution services in China, Korea, and even individual games like League of Legends have higher concurrent numbers than Steam.
You have a narrow view on what's competitive.
It is uncompetitive on PC space.
China is mostly a walled market and Korea do not have the China size to form any kind of competition.
Generally speaking, the ecosystem battle in the West ( and hence by proxy the World ) heavily favours American companies because of its market size over other western countries and English being the universal language.
It's a cultural dominance over the rest of the world because you only need to win over America and it becomes winner-takes-it-all for the rest of the world and for a very long time in the distant future.
You could even become like Facebook and uses your newfound wealth to buy over early upstarts similar to yours. Instagram took the money while snapchat says no at $3 billion.
Valve has a kind of dominance on the PC market that I do not see being challenged whatsoever. At best, Tencent would keep its China market and that's it.
The only real form of competition would be mobile games, kinda like what it did to traditional handheld segment but this takes time to replace and compete the kind of experience you can get on PC.
