I like to play KOEI’s game, especially Romance of the Three Kingdoms (San Goku Shi). It is related to the real world management.
When playing the game, we need to first build a kingdom. Then, the player should found that, if the kingdom has only one character (officer), the kingdom can do nothing, because each character can do only one task (or limited tasks) for each month. Even the character has maximum status values: intelligence 100, war 100, politic 100, charisma 100, though the character is useful, the kingdom itself is useless. Thus, the player needs to recruit more officers to work for the kingdom.
For recruiting the officers, there is a problem. It is difficult to recruit good officer. Because some of the good officer is already work for other kingdom. Simply recruiting any officer also has a problem, especially there are some useless officers. Recruiting these useless officers does not help much in a small kingdom. This is because they cannot work for the kingdom, they cannot contribute anything. Yet, the kingdom need to pay for the officers every month.
To increase the income of a kingdom, the kingdom must have lands, then the officers need to develop the land for economic growth to earn money seasonally; or to develop the land for farming to increase the food supply for every year. Therefore, in order to make a kingdom strong, the kingdom must develop to get the income. Yet, the features of the land is also important, because some of the lands are not fertile. This is exactly same as the real world, that is why some of the country are rich of resources, yet the other not.
One of the feature of San Goku Shi I like is the compatibility value of each character. This is a hidden value, one can only see it with the character editor in Power-up Kit. The value range is from 0 to 149. When the two characters has the compatibility values which are close, they are easily to get together, and 0 is close to 149 as a cycle. So, Cao Cao is 25, Liu Bei is 75, and Sun Quan is 125. Their innate enemies are the value Yuan Shao (almost 100), Dong Zhuo (almost 0), and Liu Biao (almost 50). Therefore, a kingdom will always has a group of people which has similar compatibility value. This is exactly same as the real world, that is why people are normally divided into groups with the similar characteristic.
Therefore, a kingdom, not only needs the lands for the resource, good officers to work, and also the opportunities. They are important factors: 天（时）、地（利）、人（合）. With these factors, the player can build a strong kingdom.
