Not if the target's belly is protected by armor.
Technically, groin/eye shot was an option to go for a low chance to hit, but without armor modifiers, and a chance for instant death, or falling on the ground/disabling. It's a tactical choice. The question is, does bethesda's engine support armor modifiers in a way that it would make sense to include that kind of called shots?
Well, yes, the lulz were all in the text description... if it's not saying "female raider gets hit in the groin for 654 HP, her fertile days are over" or so, it's just a bloody animation, nothing funny about it.
well, because it's role-playing...
No.
Called shots have nothing to do with role-playing. The mere presence of an option for the player is not role-playing. If that were the case, Halo giving me a selection of guns is a role-playing element.
Aw come on.
It's definately not a key roleplay element, but it adds to it if you have a little imagination: A character that's cowardly, and not very good in fighting, will likely kick the groin to bide some time and run for it, while a fighter will bash the head until it breaks open, a sniper will go for the eye, etc. At least that's how i was playing it, and found the system very rewarding.
Anyway, it's just special called shots with various effects. I think people insist specifically on groin shots, because it's funny. Not "guy gets smacked in the balls" funny, but "In fallout 3, nobody has reproductive organs, like in Mickey Mouse" funny. get it?
