The world around you and your dynasty rearranges itself again and again - all non-player figures make their own decisions. What does it mean in practice you might ask? The World is rearranging itself and changing constantly. For example, prices of various products on the market are going to change depending on diseases, wars etc. You have to react to such changes in order to become someone important. Furthermore, as soon as your economical empire is going to flourish, prideful NPC-s are going to react badly, thus being less willing to help you. Remember that the Europe of middle ages is a harsh World. However, with your intelligence and wits, you will be able to prosper.
In The Guild 3 societies can be compared to very powerful social clubs. Normal guilds like Freemasons or Smith’s Guild, are publicly known, while others prefer to remain in shadows. It is up to you with whom you are going to forge an alliance and who will be your enemy. Remember though, that the society is not going to react positively if you will be a member of Thief's Guild. Use each guild for your own benefits.
Your career in the city starts slowly. However, as the time is going to progress your dynasty is going to flourish and build new districts within the region. Soon enough, you are going to realize that you are not the only one. New neighborhoods are being created within a city through political intervention, general rise in population or other circumstances. Thanks to this you are going to feel like a part of the society.
At the very beginning of each game, you are provided with only one task "Forge your own dynasty". It is entirely up to you how you are going to do it. You can be a good guy merchant, who provides people with various goods. On the other hand, you might turn into a bad guy, who takes control over the city with brute force and fear. Or maybe you prefer to pull the strings from behind the shadows? There are endless possibilities which you can choose. Thanks to this, the game has a high replaying value. Each gameplay is going to be different.
