As some of you may know , Steam is the first gaming platform that made price adjustments for Russia and Turkey. I think Turkey and Russia is most crowded and poor market in gaming. However I don't know if its a lucrative decision for Steam because they don't share anything and you can't reach any data about it.
However when you look the PS4 Games they are like super expensive and a lot of people doesn't even buy consoles or they just play Fifa , as an instance Devil May Cry 5 was 500 Turkish Liras in the first release now its 400 Liras and monthly average wage in Turkey is 1500 Turkish liras so if you want to buy the game its 1/3 of y our wage.
I think price adjustments for each and individual country would be a better choice for the future.
