Western kids game doesn't have much to it (5)
I believe the answer is:
wispy
'game doesn't have much to it' is the definition.
I can't judge whether this definition defines the answer.
'western kids' is the wordplay.
'western' becomes 'w'.
'kids' becomes 'ispy' (I am not sure about this - if you are sure you should believe this answer much more).
'w'+'ispy'='WISPY'
Can you help me to learn more?
(Other definitions for wispy that I've seen before include "Lacking in distinction" , "In thin strands" , "Flimsy" , "Slender and delicate" , "Straggly" .)
