The concept is somewhat tested in various Law Enforcement training - There is a range within which it takes longer to draw your weapon and aim and fire than it does for a melee attacker to close and deliver a probably lethal blow. The distance obviously varies with the weapons, but that's the rationale as I understand it of a minimum range for certain weapons.Edited By: Kay Dallben on Year 18 Day 65 10:17
Assuming the situation is always: "I have my weapon drawn and aimed", yeah that distance is pretty much negligible. It's equally possible, since our combat system is not so sophisticated to take into account true Distances, readiness, etc., that every round an opponent is closer to you than the minimum gun range, you're too busy trying to fend off their attacks to take a full separate action to aim and fire - even into a belly or whatever you people think is so easy with a swordsman attacking you when you have a mid to long-range rifle. Albeit that suggests some kind of minimal "melee" action is necessary for any given Rifle, we can assume that minimal action is negligible in the grim dark realities of Star Wars.
Keep in mind, whatever links to realism or arguments along those bases, the combat system is entirely a simulation of combat. Hell, HP makes no actual damn sense. RPG systems and games just use it as an abstract measurement of one's ability to survive in combat long enough to get a lucky kill/disabling shot in because we have to be able to differentiate characters beyond simple skill choices. Obviously a single lightsabre hit or blaster bolt OUGHT to kill you, but they don't. Some people blame Armour, but I prefer to just look at the system as a whole to simulate the chaos of combat. IE: higher HP of people can be viewed as just having a higher level of skill at reading their opponent which gives bonuses to a) avoiding damage; and/or b) forcing the attacker to parry or dodge or avoid instead of aiming/stabbing/whatevs. A Battle on the whole ends up being decided by whoever gets sufficient number and magnitude of advantages to reduce HP to zero (IE: whoever manages to defeat the defenses and avoid the offenses of their opponent).
And PS: The Shotty is min range 0, so why are you all arguing about Shotties being gimped in Melee range?
