I’ll grant that a looot of valve’s revenue is from marketplace & steam store, and sure they sell other products but it’s a drop in the bucket vs gaming. It’s effectively a service for gamers. It’s probably not considered gaming revenue for accounting/internal politics reasons.
I would wager that if it were possible to, you’d be able to link a vast majority of valve’s revenue to the purpose of gaming. Reality vs financial reality?
For me, I don’t mind that they re-release tesv on whatever potato they can fit it on, it’s that they keep doing this for over 10 years, but where tesvi? Maybe they got grrm writing it.
