My idol, SunTzu, meaningfully states and stresses the 5 laws of an army.
The art of war, then, is governed by five constant factors, to be taken into account in one's deliberations, when seeking to determine the conditions obtaining in the field. These are: (1) The Moral Law; (2) Heaven; (3) Earth; (4) The Commander; (5) Method and discipline.
- Sun Tzu
Even in simple games like Chess and League of Legends, simple viable strategies and rules that are the foundations of battle are important, for the most part, to secure victory.
