One very important aspect that correlates with the tactics is the awareness of the character. Some common factors can make part of the awareness of an AI character such as audio, vision, and perception, for example. These factors are inspired on the human features that we all have, vision, audio, touch, and perception of what is happening around us.
Therefore, what we are looking for is to create artificial intelligent characters that can process all of that information at the same time that they are doing other things making them aware of the surroundings, making better judgment of what decisions should be taken on that given moment.
