Collector's Editions and their Territories

[Solemn_In_Berlin]

So yeah, I never quite understood why some CEs are exclusive to certain territories. It's puzzling to know that Europe almost always gets the best editions, even if it seems plausible that those same editions can be offered to, say, North America. I mean, I get why small/niche companies like NIS America and Ghostlight can only offer their CEs to region they're from, but the same thing can't be said about big-name publishers like Ubisoft and Square Enix. So yeah, I don't understand why a collector's edition can be different depending on where you're from. Does anyone have an idea on why this is so?
