Some indie devs quickly turn countries like Brazil from their largest piracy market to their largest actual market just by giving them a bigger discount.
Russia is another great example of that. Steam prices were historically very low due to ubiquitous software piracy. It was so widespread that even large computer stores would sell pirated games. AAA game publishers had to put their games on Steam with region locking at up to 10x discounts for people to actually buy them. Then prices steadily creeped up as more and more people started to purchase games
I mostly buy games by selling crates that I get in counter strike. It's just not worth it otherwise
