This has been the trend since early 2010. More and more games made by small companies are exploding and outselling AAA games. Stardew Valley had its all time peak 2 months ago despite being 8 years old, Dave the Diver popped off last year, Helldivers 2 broke records before Sony decided to fuck it up and subsequently get dragged through the mud, and Hades 2 is apparently awesome.
The slow death of AAA games has been great to watch. There's so much more variety than 5 years ago and you don't have to give your money to soulless corporations to enjoy them.
People are already paying for ads in games. Look at American/European truck simulator where you pay to have Goodyear or whatever other company on your rig.
If they do it tastefully.. like a coke can in a cafeteria which would make it more realistic than a generic brand - it could work.
They’ve been doing this in movies for decades.
If it’s shit like pop ups or little red notification dots, they can go fuck themselves with a rusty screwdriver.
