Running advance press, featuring current game (5,8)
I believe the answer is:
space invaders
'game' is the definition.
(Space Invaders is a video game)
'running advance press featuring current' is the wordplay.
'running' indicates anagramming the letters.
'featuring' means one lot of letters goes inside another.
'current' becomes 'I' (symbol for electric current).
'advance'+'press'='advancepress'
'advancepress' with letters rearranged gives 'spacenvaders'.
'spacenvaders' going around 'i' is 'SPACE INVADERS'.
(Other definitions for space invaders that I've seen before include "Early computer game" , "Early electronic game" , "Early arcade game -- aliens?" , "They'll leave you little room" .)
