Bro UK is still in the EMEA and Europe region regardless if The UK isn't in the European Union or not lol. No one has ever referred to EU when talking about games as the "European Union." It's just referred to the European region which the UK is in lol.
Can never know nowadays. I’ve seen someone make the same argument claiming UK isn’t part of the eu region anymore because UK isn’t in the European Union lol.
You really seem to misunderstand the definition of a region, lol. Politics has absolutely nothing to do with it; the UK is geographically and culturally part of Europe, and that will never change.
