Wargaming used to be an obscure hobby, but now the UK's population has some awareness of wargaming.The evidence for this:
The BBC mentions wargames once a month- in the context of cyber wargames e.g. in City of London, military wargames e.g. gaming threat to Baltic Republics.Over 90% of the 24 to 38 years olds (so called Millennials, Generation Y, Gen Next, were aware of role-playing e.g. Dungeons and Dragons). Sales of Dungeons and Dragons are seeing resurgence.
Practically all large business run business wargames (i.e. business continuity exercises).
Many UK bookshops sell Euro type board games that are certainly in the wargaming space.
The UK Health Service, local government and public utilities, run wargames in the form of emergency planning exercises at least annually.
Games Workshop and Warhammer are a high street brand image- currently valued at £962 million.A local wargaming show at Devizes (which is a rural area of Wiltshire, UK) had attendence of 1,100 people.
Wargaming seems to be established in the UK as a cultural norm. Who could have predicted that ten years ago?
