In the last half of the 20th century, science gave many examples of complex phenomena can arise from simple rules and simple equations. Chaos Theory and Multi Agent Systems were among the fields the were born when scientists realized this. For game development this is really important, because you have to give an imersive, fun and realistic (looking at least) expirience to the player, and this must be done at least 40 frames per second. One of the most important aspects of game simulation that leads to imersion is the movement of the characters throughout the game environment. That’s what Steering is for.
