Game originally called "La Conquête du Monde” (4)
I believe the answer is:
risk
'game originally called la conquete du monde' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for risk that I've seen before include "Assessment of potential dangers -- any silk saris (anag)" , "dangerous thing" , "Take a chance" , "Possibility of bad outcome" , "Danger or hazard" .)
