Depends on what price the developer chooses and how stable the exchange rate between USD & the local currency is. If the currency gets weaker and weaker compared to the dollar, then the real price that locals are paying will go up.
And, I’m pretty sure that local inflation rates are the primary driver of this change. So, yeah, games will likely get more expensive as inflation continues & developers don’t constantly update the USD list price.
Spot rate pricing for electricity is uncommon among households for exactly this reason. The price is most likely the result of energy market conditions, rather than nefarious actors in the market intentionally manipulating market conditions.
Usually there’s a company that would be absorbing that risk of price fluctuations by charging slightly more than the baseline normal so that they can afford to charge households at a loss for the short periods where the price spikes as insanely as this.
