"Of It's Time" : Rooted in the 1980's ZX Spectrum Software (aka Culturally "Out of Date" stuff)
This does not have to be UK based but it has to be ZX Spectrum software that is culturally specific to or at least strongly related to the 1980s . One clue or "give away" would be that it seems out of date now !
I have got one:- Do we still have "streakers now" ? Well I have one "Streakers" by Bulldog Software ( I am not surprised a Bulldog would probably like a Streaker "oo yum yum"!)
