Hmm. Actually, no. You missunderstand me. Unique quests are the realm of GMs and Settings writters. Coded quests, in my mind, should be able to be RPed as if you are just one in a long line of people that have tried to do said quest (as you are). As most of them are written that I have tried, you are the first person to ever try to help the NPC, and once you are done, said NPC should not need any more help on that subject.
I give a tiny example of a made up get-this-item quest that could come in two versons.
>Can I help you?
NPC> Actually, yes you can. You see, I am in need of a special scroll that was lost in the sewers. Will you get it for me?
>Yes.
NPC> Great! It is to be found somewhere deep in the twists and turns. My assistant, Reen, has not yet returned form his search either.
Go to sewers, find Reen, who has found the scroll, but got lost. Talk him into giving you the scroll and return.
>I have your scroll. -give to NPC-
>Thanks! This is exactly what I needed, and I can now complete my research. Here is a little reward for your help.
Another player comes up to NPC>Can I help you?
NPC> Actually, yes you can. You see, I am in need of a specail scroll that was lost in the sewers. Will you get it for me?
>Yes.
NPC> Great! It is to be found somewhere deep in the twists and turns. My assistant, Reen, has not yet returned form his search either.
Go to sewers, find Reen, who has found the scroll, but got lost. Talk him into giving you the scroll and return.
>I have your scroll. -give to NPC-
>Thanks! This is exactly what I needed, and I can now complete my research. Here is a little reward for your help.
Two players meet.
>I just helped NPC find this scroll to finish his research, and helped Reen get out of the sewers.
Player B tries to RP> Um... I just did the same thing... how did he lose his scroll so fast again? Do you think Reen is stealing it?
/tell>[[It is just a quest. Thousands of people have done it before, and thousands of people will do it again. I don't think they are meant to be used in player to player RP.]]
Verson two.
>Can I help you?
NPC looks up from a pile of disorganized papers, and sighs.
NPC> Well, no one else has been able to yet, but maybe you will be the one! You see, a one eyed rat grabbed an important scroll I need to complete my research. My assistant, Reen, chased it down to the sewers. He went down there some time ago to try again. Would you be kind enough to see if he has found it yet?
>Yes.
>Good, good! Maybe this time it will be found.
Go to the sewers and find Reen, who does not seem all to bright.
>Do you have the scroll?
Reen> Well... I think I have it this time, but it is hard to tell. It is kind of soggy. You want to take it back? I'll keep looking, just in case.
Reen gives you the soggy paper. You take it back and give it to NPC.
NPC> Drat and double drat. This is not it either. Oh, my research will never be completed at this rate. Don't feel bad. No one else could find it either. Here take this for your efforts, though. No need to go back down to the sewers again, as someone esle just offered to help. Thank you again.
NPC gives you some potions, a useful scroll, a bit of free training, or some such.
Player B does the same quest, then comes to talk to player one.
Player B> I just tried to help out NPC.
>Ya, so did I. Poor guy. What do you think he is working on?
PB> I don't know, but he should get another assistant. Reen does not seem too bright. You did not have any luck either?
Laughs.
>Ya, I noticed that. And no, no luck. Maybe someone else will have better.
