Management is a game for the Palm OS. It works on colour, grey-scale and black & white models.
The game involves buying raw materials (plastic, wood & metal), manufacturing them into finished goods and then selling those goods.
Prices of the raw materials and finished goods are determined by who is buying/selling how much each month. So in that way, it is a microcosm of a market economy. The aim is to have the most cash at the end of the month. Tactics are used to ensure that only you can buy a particular item, etc.
