Condition limiting new game leads to anger (7)
I believe the answer is:
inflame
'anger' is the definition.
(I've seen this before)
'condition limiting new game' is the wordplay.
'condition' becomes 'if' (I've seen this in other clues).
'limiting' indicates putting letters inside.
'new' becomes 'n'.
'game' becomes 'lame' (I've seen this before**).
'if' enclosing 'n' is 'inf'.
'inf'+'lame'='INFLAME'
'leads to' acts as a link.
(Other definitions for inflame that I've seen before include "Make (a situation) worse" , "Excite passionate feelings" , "Bother" , "Be provocative" , "Incite" .)
