Imperialist game? (8)
I believe the answer is:
napoleon
This clue might be a double definition.
'imperialist' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'game?' is the second definition.
(I know that Napoleon is a card game)
Can you help me to learn more?
(Other definitions for napoleon that I've seen before include "A pig farmer was chased by" , "Extended nap" , "Frenchman known as The Little Corporal" , "No one, pal, matches this Little Corporal" , "card game" .)
