It seems like no one in the other Destiny threads doesn't know the answer, so I'll ask here:
Is it safe as a EU PS4 player to get the Digital Deluxe Super Edition from the US PS store? It's almost 30 euros cheaper on the US store :O
I can't say for sure, but as I understand it, you would need a US PSN account to activate any PSN codes, if you then make that US account the primary on your console you could play on your EU account with full access to everything. I also think you would have to buy all future expansions on the US account, but I'm less sure about that.
