Its extra funny that someone is lording his knowledge of "VATS" over Ben in the comments given that they can't even bother to lord over Ben with correct information. Shooting for the groin confers a high knockdown chance, knockdowns basically paralyze most humanoid opponents (they use too much ap standing up to shoot) and as L1ama pointed out you (and your followers) get a large to hit bonus. This is especially valuable when you have low to mid values on attack skills and are never gonna hit anyone in the eyes. Also the mechanic is named "Called Shots" in Fallouts 1 & 2, from GURPS (which S.P.E.C.I.A.L. is adapted from).
As a person who played (and has been playing) these games since they were new, Ben is doing a pretty well for a game as obtuse and arcane as this. That jet addition is gonna haunt you though....
@cyraxible: @arzonk: there is a time limit in 2 but it is several years.
also hot tip for @benpack, never let sulik hold a knife in his inventory his ai loves to switch from whatever good weapon you've given him to any old knife mid-combat
