For the hundreds of millions of gamers allegedly on Steam, the income is very low.
Last real data was 2021 because a trial, and it was 2 billion for Valve, so probably some 7-8 billion overall. Since then it's probably a bit more, specially adding Steam Deck sales and all. 10 billion, 12 maybe. For having like 200m active users monthly and getting that after Newzoo half the playtime comes from GAS, it's not so much. Oh, and the gambling with loot boxes.
I think that's why the other poster said that, they spend big money in the rig, but then play the uncle scrooge or jack sparrow game about buying games. Selling anything over 25 is very hard on Steam, some other publisher said these days.
I mean, in the Newzoo report it was stated only 5% of Steam users buy games released in the current year and at full price or nearly.
Most users wait for heavy discount sales, buy very old games, or buy pirated keys in those online stores and then activate them on Steam as part of their library.
