You know, when you think about it, even NPC\'s shouldn\'t be allowed to sell 24/7....
Think realisticly, there are no merchants with an unlimited amount of items. Even a player merchant would have to go and get new items periodically. But I do like the idea of having NPC\'s staff shops and so forth...
About the quests, sure there should be SOME newb orientation quests.... But besides that... the players will automatically make quests themselves without realizing it! Think about it, especially in a guild where you will have to get items for fellow guildmembers, perform special missions to get promoted, go training with your fellow members, and even going on war related campaigns against other guilds. Now I admit, this will be harder for the freelancers, but it would still work. And it would be TONS better than having thousands of people doing the same quest, over and over and over again. I mean here is a hypothetical scenario... The Blitzers guild has found a new crystal mine, but it is very hard to access because there is a BIG river seperating it from the Blitzers Guild House. So we hire bridge builders from Bloodclaw to make a bridge there... and voila! Quest made for the Bloodclaw members! They have to gather supplies, find the best spot to make the bridge, make designs for the bridge, build the bridge, and build it again if it collapses!
I think the whole idea of this being a Roleplaying game is that the quests will make themselves after a while... especially after all the functions in the game are put in.
Ah, and here is something I posted a couple of months ago about how a quest could be triggered if a spell went bad...
For example:
If you are a necromancer/shaman/spirit-talker (whatever), and you are summoning the spirit of a long dead persona. Now this persona was extremely powerful in his lifetime, so summoning his soul is going to take quite a bit of determination and skill. BUT, all of a sudden, something\'s gone bad! For some reason, you can\'t control the spell, and instead of summoning the soul of the already dead person, you partition your soul into two parts. Now there are two of you! An NPC (which would have to move and fight and the like), and you. And you have to figure out how to make your soul one now.
This is an interesting idea, because this could trigger a quest also. It\'s also interesting because of the NPC concept. This NPC could be online only when you are online.. because it is your second half. And you would have to perform a certain spell/eat a certain herb/whatever to get your soul in one piece again.
As you see... I don\'t think that we will need (waaaaay into the future when all the functions are put in) NPC triggered quests at all! I for one would like the world to evolve and have different quests all the time.
