Thing isn't in benefiting underpriced games for Russia, thing is in hyperinflated prices in US.
Cause - US prints money without heavy loss of currency's value. Money is used to buy things in other countries, and regularly return in big chunks with bribed/corrupt foreigners which flee from defaulted countries, like Berezovsky from Russia or Saakashvili from Georgia.
These people can afford big spendings, capitalists, ho, up their prices(rent, food, education, everything...) , because there are people who can afford them, companies then increase wages to accommodate for bigger spendings of their workers, more money in the area - you can up prices even more...

Let's take hypothetical situation - you need to buy bananas from Zimbabwe. They say: $100 our dollars for banana, and flat price $1 zimbabwe=$1 US.
You know that they print money in trillions, and their wage gives $100000 Zimbabwe for the same job you do for $100 US.
Fair rate should be different, but... Zimbabwe doesn't need US dollars. Demand/supply curve.
In real life world trades oil as bananas, and US is this Zimbabwe.
How harsh is hyperinflation... Who knows.
I got 2 specialist engineering degrees in Russia (equiv of Master) for $1k total. My brother got Master degree in computer design for $5k, now works in company which sells animation to Nickelodeon. As I have seen, these same courses would cost 10-20 times more in US.
Food? ~$8 for kg of perfect bacon. Imported chocolate $0.8/100g
Communal payments? I pay ~$50 monthly.

If games cost close to average monthly wage - who would buy them?
With digital distribution producers have choice - squeeze some more money for the price of electrical bill or not getting anything.
