Someone knows where I can Buy Sekiro for a good price?

Like the wages are different for each country but also living expenses etc you mean.

Yeah, it's like the same thing with saying, oh, It's harder to live in USA than europe because the game prices are quite cheaper because 1$ = 0.89 eur. Quite stupid thing to write or say, imo...
Polish people be like, we kind of feel you bro, it's 1$ = 3.83 PLN. 😅

I think it might help compare purchasing power if I mention that the current legal minimum monthly wage in Brazil for a 44-hour-per-week job (usually, that means 8h-12h, 14h-18h, Monday through Friday, plus 8h-12h Saturday) is 1412 BRL. The exchange rate has varied wildly recently, but taking that 5.42 as reference, that's 260.52 USD per month. A 44-hour-per-week month has 190.67 work hours in it, so that's about 1.36 USD per hour.

The game's current price on the store is 274.00 BRL. Converting the monthly minimum wage to hourly results in 7.40 BRL/hour (= 1.36 USD/hour). That's 37 hours of work for the game at full price, or almost a full week. Meaning, it's not exactly pocket change. Games in general are an expensive commodity, but 274 BRL is honestly well into the territory of what I'd consider ridiculous; I outright refuse to shell out that much money for a game.

Granted, there are plenty more factors (besides, you could argue that someone earning the Brazilian minimum wage isn't buying full-price AAA games on Steam because they have to channel that money into first-degree necessities such as food, and you'd be right), but this is an easy one if you just want a basic overview to have a general idea of what the landscape is like.

Its probably the ignorant and shitty economics lesson as an non-answer to a simple straightforward query.
