Lacking pennies after video game (6)
I believe the answer is:
devoid
'lacking' is the definition.
(I've seen this before)
'pennies after video game' is the wordplay.
'pennies' becomes 'd' (abbreviation e.g. Lsd - pounds, shillings, pence).
'after' says to put letters next to each other.
'game' indicates anagramming the letters (the letters play around).
'video' is an anagram of 'devoi'.
'd' put after 'devoi' is 'DEVOID'.
(Other definitions for devoid that I've seen before include "Empty - do dive (anag)" , "Completely lacking" , "Lacking or free from" , "Free (of something)" , "Entirely free (of)" .)
