I agree with Xandria about the fact that Planeshift\'s method of NPC-Player communication is fine as it is. Like Xandria already said, the method requires people to think, not mindlessly click. Or push buttons. The method suggested, while many RPGs have it, does have its limitations, many of which are major. Wizardry 8 had you type in something to talk to a NPC, and it was interesting doing that, in my opinion.
Anyway, limitations of the suggested method are all too obvious. One, you can only say certain things to certain people. Not realistic. For another, you can\'t ask anyone for recent news, what\'s happening, where you are if you\'re lost in a city, and so on. I\'d rather have a smith give me directions if I were lost than have him/her force me to buy a copper knife.
So maybe you don\'t want to talk to loads of NPCs looking for a quest to do and only 1 out of 100 has one for you. Neither do I. However, there is this really cool thing called \'asking.\' Here is how it would work. You ask for a quest. NPC does not have one for you, but knows where you can get one. You ask where you can get one, and NPC answers. Also, perhaps there can be tones of voices, like threatening, polite, angry, drunk, and so on.
Also, speaking with NPCs with the chatbox thingamajig can be used for asking how you do a certain thing. I remember in RS I could not figure out a way to milk a cow. I tried using a jug, but it failed every time. I was too embarresed to ask anyone else. Perhaps NPCs can help out with things that you can\'t get the courage to ask other players about. Of course, there is always the chance the NPC will point and laugh at you...
Just my confused thoughts on, erm, paper.
