And going off of what Yujo said, barriers aren't the only things that make the IC hunts something of a challenge, though I agree with what he said fully. Huh, funny how that keeps happening lately.
Regardless, it is also the people of the village itself. I'm going to use myself as an example, let's say that I'm the host of the Six Tails again, and someone comes searching for me while I'm in Uzushio. Even taking away what barriers we do have, he gets inside, finds me, and what? Asks me to step outside with him? Away from everyone? While he is at it, might as hell to just ask me to hang myself for him, too >>
Nah, if someone actually did all that, I would want to step outside and have a fight.
BUT, for the sake of the example, let's say I say no. And he attacks, or hell, let's just say he attacks me right off the bat. Well, of course I am going to defend myself and demolish this fool to the best of my abilities... But I'm sure that none of my children would want to stand off to the side while I fight some dude through the streets of Uzushiogakure... Well, maybe Rikudo, but that is besides the point. So with my children alone, this dude is fighting me and no less than four other people. Then Keito is gonna get in on it because we go waaayyy back, plus he's the Kage, and he isn't gonna want people thinking Uzushio is full of pushovers. So this man comes down with his pimp hand ready, adding to the total count.
And then Yujo comes along cause me and his pops go way back, too. And he just looks at the man and turns him to ice, cause that's his thing. And then Rikudo notices the slaughter-fest going on and decides that he wants to get in on it for some good ol' fashioned family bonding.
And even after all that, the old lady that Athos helped that one time down the street decides to grasp her ladle in her hand, wielding the lid for a pot as a shield, before charging into battle. And that show of heroism causes all the people of Uzushio to bear arms and to attack this person.
And I haven't even mentioned the NPC guards, ANBU, Death Knights, Manji ANBU...
Do you see what I'm getting at? I would love the idea of IC hunts and putting some rules down, but that begs the question, to what levels can we place rules on this before it is just scripted and stopping people from doing their casual RPs in their villages or whatever? o.o
