More exciting city (4)
I believe the answer is:
rome
'city' is the definition.
(Rome is an example)
'more exciting' is the wordplay.
'exciting' is an anagram indicator.
'more' with letters rearranged gives 'ROME'.
(Other definitions for rome that I've seen before include "Basis for cheese" , "Italian city" , "Seat of Italian empire" , "Capital of Italy" , "All roads lead to it" .)
