Its just to bad that when your role playing, and your really into your character, that you can't just haul off and kick an NPC in their nether regions when they get to pushy.
It says right here in the contract you signed, "I will not sue for assault if I get kicked in the nuts". You knew what you were signing up for!That would be an excellent option for the game. Wouldn't take too much work. Hire an actor. Put him in a mocap suit. Then surprise him with a kick to the balls. That way you get a more natural reaction.
