Note: Quest For Glory 3 introduces a toolbar instead of manually typing in commands as in the last two games. If you are unfamiliar with this method here are some pointers.
Speaking- You can ask questions by clicking the mouth icon on the person you wish to speack with. You can make statements to the person by clicking the speak icon on yourself.
Purchasing- You can purchase goods by clicking your money pouch on the merchant that you wish to purchase from or by clicking the talk icon on yourself and selecting 'purchase goods'.
 

Walkthrough:

Starting off
    You are in the house of Rakeesh and his wife Kreesha, begin by questioning each of them on all topics (and run-off topics). Once you have done this leave the house (the exit is on the top left corner) and go across to the building with two doors. You will be welcomed by the welcome woman, you can sit and eat (you  wont be charged). Head upstairs to your room, leave the inn.

    There are a few things that you should get while you are here, but first you have to exchange your money. Head down the stairs the the bazaar, go northwest and you will witness a dispute. You can either chase the criminal or trip him by knocking over the fruit basket, either way you will have to go to the 'hall of justice.' After sceens of the council and Rajah, the king you will be let out. If you are the magic user it is important the you go south into Kreesha's house, she should be lying on the floor reading, ask her about magic and she will mention a ritual, keep this conversation in mind.
    Now to get the stuff. Go back to the man who was being robbed, click the mouth on him then on yourself and 'say yes' to exchanging the money. Go to the leather merchant on that same screen and buy 2 waterskins and 5 zebra skins. Go to the bazaar entrance and buy 1 fine spear and 1 fine dagger from the weapon seller, Buy oil if you are a theif (from the oil seller), buy honey, and a tinderbox from the junk dealers (you do not have to buy this as a magic user). Go south, buy beads (you can't bargain), and if you are a theif buy a rope and inquire about acrobatics lessons (give the rope seller the theif sign). Again go south, start by clicking the money pouch on the drummer. Go to the woman and buy a robe. Buy about 50 meat from the dog guy, he will bargain to 1 cent. Go to the Katta creature, give him th 'note from shema' from your inventory, then try to buy a sculpture, you will get it for free, also tell the cat about Shapeir. The other thing you should do is visit the temple (the highest door in the town) and talk to the lion there.

    This includes everything that you need to do while you are here. If your two days are up or you run out of money don't worry you can get some of these things later.

    If you have extra time you can talk to the apothacary about the dispel potion.

Simbani village
    After two days you should go to the Simbani villiage, where Uhura lives. Once you arrive, you are sent to speak with the Simbani leader, the Laibon, be respectful and gain all the knoweledge you can. When you leave you will end up in Uhura's hut, question her and Rakeesh and you apparently go to a celebration in the village, then back to your hut with Rakeesh. You can question him if you like, then go to sleep. When you wake up he will be gone.

    Over the next few days there are several tasks that you have to perform before the game can progress:

The magic user
    The wizard has to preform the magic staff ritual to complete this game. The first thing you have to do (assuming you have talked to Kreesha) is visit the giant tree in the jungle. Go into the lower area (where the guardian is) and speak with it, ask about the 'wood', the guardian will inform you on what you have to do. Next, walk around the ant hill area in the jungle, eventually you will come to a screen with blue orchids. You can either levitate and grab the flowers, or cast fetch to get them (fetch is alot easier). Once you have the orchids you must dip them into the pool of peace at nightime. Once you have done this go back to the giant tree, this time go to the top area of the tree and place the orchids on the platform and take the wood. Later (whenever you want) you can visit Kreesha and perform the ritual (it is all automatic once you reach her house).
