the moving around alot in a shop would be a nice addition, and like when they ask ya something ill use this as an example:
Shopkeeper: Why do you keep walking around so much in my store, is it that big?
Player:(option 1)Im trying to figure out what i want to buy
(option 2) im fixing to steal something
(option 3) mind your own business
Shopkeeper: (option 1) well hurry up ive got more things to worry about then some customer who cant make up his mind
(option 2) GUARDS!!!!!
(option 3) well fine, but mind ur own business someplace else (or something of the sort)
option 1: the better of the 3

option 2: the i wanna be stupid for fun kinda way
option 3: the i wanna get thrown out cause he kept asking me questions kinda way
i\'d like this, it\'d be fun to every once in awhile be stupid, get thrown in jail, and then released after a certain time (since u didnt really steal anything), but while ur in jail u should have some ppl to talk to, such as a hole in the wall so u can talk to other prisoners and maybe find out some \"very valueable info\" or u can just sit till they release ya :S, of course its always a good thing to get the item first before u decide somethin like that
and i dont like the idea on how running in the streets would get ya tackled and arrested even though that\'d be funny as hell if a player could tackle another player while running just for laughs (and to piss off the other player) but only if its in PvP
u shouldnt get arrested cause what if ur in a hurry? maybe u ALMOST forgot to go see someone?, it might give ya a good excuse if u got arrested but its still not needed, but running in certain buildings or on a certain route might be suspicious
and finaly the last of my post (thank god, eh?)
having special quests to find \"suspicious looking characters\" (characters = NPCs of course), i think that\'d be fun, as long as u got something special, or could like hit him over the head, and drag him back to the person or something

(of course u\'d have to get him into an alleyway at first)
