Game requiring forbearance (8)
I believe the answer is:
patience
I believe this clue is a double definition.
'game' is the first definition.
(patience is a kind of game)
'forbearance' is the second definition.
(synonyms)
'requiring' is the link.
(Other definitions for patience that I've seen before include "Work by G&S" , "Gilbert and Sullivan work" , "Game, tolerance of delay" , "Composure" , "Waiting calmly" .)
