The legal aspects involve contests and lotteries. Every country has them and, including The USA and Canada, each state or province has their own laws.
Even in the US, not all contests get legal approval in each state. For example, a lot of contests will restrict them to the mainland 48 states. In Canada, Quebec makes it very difficult to have a countrywide contest. I am sure Europe and Australia are all the same, too, with each country having their own laws. SONY needs legal approvals in each one. That shouldn't restrict them from letting us get access to the on-line download, so I have no idea why that happened, this year. Something made them do it.
However, I have asked about the SCEE restrictions in certain countries, was told it would be looked into, but I am not sure I will ever get an answer.
Thanks for the info. & appreciate that you have at least asked!
