So they can create a PSN account, it would just have to be one from a supported country like the USA, in which case they'd need to enter a valid US address I think?More likely this will be the template used for future games with mandatory PSN account linking. Those countries literally can't create PSN accounts because Sony doesn't offer it there.
I've had a PSN account for years and it's a US one. I live in one of those countries.
Now whether they want to go through that is another question.
