Game Leander played in halcyon days? (6,3)

I believe the answer is:

golden era

'halcyon days?' is the definition.
(halcyon days means a better time)

'game leander played' is the wordplay.
'game' becomes 'go game' (go is a board game).
'played' indicates an anagram.
'leander' with letters rearranged gives 'ldenera'.
'go'+'ldenera'='GOLDEN ERA'

'in' acts as a link.

I've seen this clue in The Independent.
