The scenario happens in almost every kind of fiction: A bad guy gets the drop on the heroes by pointing a gun at them.
In most fiction (and I daresay in real life), unless the hero is literally invulnerable to weapons (like Superman, Iron Man, or Vader in Empire), the heroes actually pause and act with caution because they know they could be seriously hurt or killed by somebody pointing at gun at them.
I'm reading the beginning of "Heir to the Empire", and some thugs get the drop on Luke using a weapon he's not familiar with. He doesn't want to fight, because he's a Jedi, but he acts with caution, instead of just saying "Oh I know my character has enough wound threshold to take at least one shot so I'll just attack them".
I feel like in RPGs, the player character knows how much wound threshold they have, and probably has a good idea of how much damage a blaster pistol might do.
In your experience, do players respond realistically or do they just take the hit and start shooting?
I'm thinking in a case like that I might give the bad guy who has the drop on them several boost dice to represent this advantage, or even an extra shot before the combat starts, because I'd like the characters to behave as though they are real people who could be mortally wounded rather than characters with a set number of hit points.
Thoughts?
