Rejected in Vietnam: capitalist game of greed (3-3)

I believe the answer is:

pac-man

'game of greed' is the definition.
(eat as many pills as possible)

'rejected in vietnam capitalist' is the wordplay.
'rejected' says the letters should be written in reverse.
'in' indicates a hidden word.
'namcap' is hidden in the letters of 'vietnam capitalist'.
'namcap' backwards is 'PAC-MAN'.

I've seen this clue in The Guardian.
