Question re: WFRP: Does the hit location determination method result in certain locations being more likely based on skill level? I would assume that if I had skill 31% then I'd have 4 chances to hit location 1 versus 3 chances to hit the other locations, but I haven't seen how they do it, so maybe I'm misinterpreting something.
RQ has a d20 with 7 locations: each arm, each leg, abdomen, chest and head, each with their own hit points and armor. Arms have less hp than legs/abdomen/head (all the same), which have less than chest. There are different charts for different body types - so a quadruped version, a winged quadruped version, etc. In the previous edition, there were two versions of the chart - one for melee, one for missile.
In general, hit locations are bookkeeping intensive with little payback for the extra effort. Its ultimately subjective whether its worth the effort, but the trend seems to be away from them as you note.
