Well, yes and no.<br/><br/>It seems that the system doesn't consist of just dueling rolls, but instead consists of two circumstantial rolls that determine the outcome of battle.  It looks a lot like the final stages of a tied tennis match.  Attacker meets or beats defender's defensive attribute, he gets an ace.  Defender counter-attacks or flees*, and if successful, forces the attacker to lose the advantage and returns the score to 60-all.  If unsuccessful, attacker wins the match.  If I recall correctly, the defender now becomes the attacker and the sequence starts all over again.  So, it is possible for the attacker to actually beat the defender's defense and not win the battle, since the defender is entitled to a riposte.<br/><br/>*Regarding fleeing, I don't really understand how it works, or rather, what the parameters for success are to initiate and succeed fleeing.<br/><br/>In my opinion, the simplicity of the system makes it a little too complex for characters outside the norm, like superheroes.  But I'm not complaining.
