Back then I doubt SEGA'd ever make events in Indonesia, but it's happening ... 30 years later.
We have a "Sega of Europe". while I am not a Londoner, at first I was afraid they would move away from London given the whole Brexit thing, but they did move elsewhere in London.
If SoE organize anything for Sega, it will likely be in London than anywhere else in Britain.
Just because I live in a country that looks like a small island on the map, doesn't mean the whole of Britain is just next door to me. Kalimantan is slightly larger than Britain, if that's a helpful comparison at all. And you can fit all of Britain within Texas.
If there is an exclusive Sega or Sonic event in London, say, the re-opening of
SegaWorld, I can't just pop onto a train and take a day-trip there on a whim.
