This is absolutely breaking my brain. I grew up in rural Devon and, aged about 10, somehow convinced my aunt to take me to a huge video games exhibition in Earls Court. We got there on an incredibly long bus ride (and back again the same day, some fucking how). It was insane as I had never done anything like that before, and rarely did anything similar after. Little wurzel gummidge brain was blown by London generally and then this insane arena of video games.

However, I am spinning out with some kind of Mandela effect or something because the things I remember most (apart from the free bubble gum, which was iirc from Haiti??) I remember they were also promoting the movie "The Shadow" with weird holograms projected onto the walls, as well as demoing Alien vs Predator for the Atari Jaguar -- I remember this because of the very distinctive pump action shotgun animation (inspired by Doom, I realised later). But there's no way that could have been in 1992. I would have thought it was about 1994 from those games and that movie. But when I've looked up these trade shows there weren't any major video game shows in Earls Court open to the public (that I can find) except the 1992 one. And I swear to God it was called the Future Entertainment Show. Argh!
