If you make the game available in Poland, you should know the basic rights.
It is unacceptable to limit the freedoms and rights of humans and citizens solely because of race, gender, language, religion or lack thereof, social origin, birth or property.
this results directly from the constitution, and changing the law during the term of the contract requires the consent of both parties to the contract, and if the other party does not consent, it may demand compensation.
So start respecting our rights. or you will lose this piece of Europe, because we Poles will not allow you to discriminate against us because of our language and not only ours. you have servers in Europe, so European law applies.
