The arcade character arrives differently
Pac-Man is not another space shooter. It has a name, a body, a maze and enemies that feel like personalities.

Hardware
Four objects explaining the month: public cabinets, home consoles, microcomputers and control technology.
Atari VCS as home arcade
By May 1980, Atari's console can plausibly sell itself as a way to bring a famous cabinet home.

Online Life
Networked play exists at the edges, but ordinary players live in a world of paper, cabinets and local knowledge.
Online life was not the ordinary visitor experience
For most players in May 1980, games are discovered through arcades, shops, magazines, clubs and word of mouth rather than online services.
Institutional networks remain the edge case
PLATO, university systems and early networked computing matter historically, but they are not normal UK consumer gaming.
Paper is still the search engine
Magazines, adverts, catalogues, manuals and club newsletters explain what machines and games exist.
The arcade is the live feed
High scores, queues and overheard advice make the cabinet a public information system.

What It Felt Like
A young medium, a patchy record, and a future split between public machines and home hardware.
01
The future was still public
The arcade feels crowded with futures: yellow characters, missile trails, wireframe tanks, talking robots and old invaders still earning coins.
02
The home shelf was changing shape
The living room is no longer just Pong. Cartridges can now promise arcade names, secret worlds and a shelf that grows.
03
Britain saw the edges first
Britain is on the edge of the home-micro era, but the arcade still feels like the brightest room in gaming.
04
The record is still uneven
Exact dates are often regional, trade-led or retrospective. The exhibit keeps month-level certainty separate from year-level context.
