I live in Bulgaria, and bought a PS5 recently. Of course, I've set the English language for my account, but since my native language is Russian I would like to play games with Russian voice acting. I understand that some games do not have Russian voice acting at all (for example, RDR2), but some of them absolutely definitely have Russian voice (God Of War, Horizon Zero Down, etc), but this is not shown for my account.
Can I change the region for my account (for example, by writing to Sony's technical support)? Will there be any problems and blocking of my console in the future?
I could create another account and set the Russian region, but the problem is that I have already bought more than 10 games on my current account and I would not want to abandon them.
