Fixed game was done poorly (4,2,3)

I believe the answer is:

good as new

I'm a little stuck... Click here to teach me more about this clue!

'fixed' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'game was done poorly' is the wordplay.
'game' becomes 'go' (go is a board game).
'poorly' is an anagram indicator (a poor spelling).
'was'+'done'='wasdone'
'wasdone' anagrammed gives 'odasnew'.
'go'+'odasnew'='GOOD AS NEW'

Can you help me to learn more?

(Another definition for good as new that I've seen is " in perfect condition".)

I've seen this clue in The Independent.
