City quietly abandoning affected game (9)
I believe the answer is:
cambridge
'city' is the definition.
(Cambridge is an example)
'quietly abandoning affected game' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'abandoning' suggests deleting specific letters.
'affected' becomes 'camp' (I've seen this before).
'game' becomes 'bridge' (bridge is a kind of game**).
'camp' with 'p' removed is 'cam'.
'cam'+'bridge'='CAMBRIDGE'
(Other definitions for cambridge that I've seen before include "East Anglian city" , "English university, rowing colour blue" , "English city" , "Light blue university?" , "Old English university" .)
