The really impressive thing about Valve is the amount of revenue they make with a relatively small head count. They have about 1/10 the number of employees as EA.
Cs:go, dota 2, artifact and underlords i think.
I guess this is estimated revenue through game sales, otherwise i’d think activision-blizzard(candy crush) and valve(steam cut, dota and cs micro transactions, steam market) would be higher.
And of course MS has an interest to undervalue some companies compared to sony and nintendo
