List some fun response.
It might be useful to model the MA population; that could stimulate transitions between the FTP Match Play arena and the MA.  In that vein:
When the AI loses:"Only way you can get a kill is to pick.  Loser."
"Nice HO shot.  Get a life."
"Took you and all your friends long enough to get me.  Dare to meet in the DA?"
"Why don't you get a real plane, let's see how that works out."
 when the AI wins:* Actually, about all you get in the MA is the occasional "<S>".  Could we break the mold and ask the victorious AI to say "Hey, good fight, let's try it again"? *
