Probably results of varied trade deals, buisnesses, colonization, and just a long history of how the world has globalized in general.

Region 5 looks like they said “screw it, let’s just throw all the countries left into a single region and call it a day”

For a second I thought maybe due to their historical colonial ties to the UK but that logic falls apart when you realize AU and NZ are in a separate region from the UK… so… 🤷‍♂️

Some things make more sense with additional context. Like, Europe was on the PAL standard while Japan was on NTSC, so even if you put them both in the same region, they couldn’t watch each other’s discs, so the region code could be re-used without it actually conflicting.

I see no borders from up here my modded console.
