Hmm, good point. A possible guideline: each vacc suit/armored suit is made for
a specific body size and form, which include different races and sexes. If
wearing a VS/AS of the wrong race (assuming the person can fit into it), there
is a -2 to -6 penalty to all physical actions. The same holds true for wearing
a suit made for the opposite sex of the same race, but the penalties would be
half of above. Of course, some combinations don't mix; an average human isn't
going to fit into a suit of droyne battle dress, and a vargr is going to have
a difficult time doing anything in a vacc suit made for an aslan. Usually,
don't bother wearing the armor/vacc suit for another race, since it hinders
more than helps. However, in the same race, and maybe even the same sex,
wearing someone else's armor might not work. Roll 1d6 each for the person
trying to wear the armor, and for the armor/vacc suit itself. If the person's
roll is equal to or greater than the armor's roll, the suit may be worn without
penalty. If the armor's roll is higher, that is the penalty for wearing the
armor. However, if the penalty is -5 or greater, then the person cannot wear
the armor in quiestion. Apply the following DMs: +1 to armor roll is person is
unusually small/large for race, +2 to armor roll if person is of wrong sex than
what armor was built for. It might be possible to make a generic armor
(actually, it seems like there would have to be one for emergency vacc suits on
commercial craft). Cost would be double normal, and there would be a -2 penalty
for all physical actions (the vacc suits don't fit anyone particularly well).
Note also that a 6 year old child could be placed in an adult human's vacc suit
for protection from vaccum -- the kid couldn't do much, but he would be sealed.
