A player made a Troll, Giant subtype, so he is 3.5 meters (11 feet, 3 inches) in height and I am wondering: are rules where it says he is any easier to hit than, say, a 1.2m dwarf?
If not it seems a bit unfair to me toward smaller targets. Yet, I just started to GM Shadowrun, so I could be overlooking something.
Assuming you're interested in 5th edition:
Run & Gun contains an optional rule (RG2, p. 108), but it's based on \$CON + STR\$, so dwarfs are usually easier to hit than humans. The following modifiers apply to the attack roll based on the sum:
$$ \begin{array}{|r|r|}\hline CON+STR&modifier\\\hline 2\text{ to }4& -1\\\hline 5\text{ to }10& 0\\\hline 11\text{ to }15& +1\\\hline \geq16& +2\\\hline \end{array} $$
There are smaller (-2 and -3) and larger (+3) modifiers, but those don't apply to metahuman sized targets.
As for fairness:
Trolls have a maximum INT that is reduced by 1. Also the cost of building a troll is extraordiarily high. Giants als have a reduced REA max.
But why is using the same modifier unfair? You knew the benefits and drawbacks of building a dwarf/troll when creating the char and size doesn't seem to be considered a advantage or drawback when determining the costs of a metatype (except for higher lifestyle cost).
