Unity's MonoBehaviours makes it really easy to make games, and they contain useful lifecycle methods and events that are automatic during collisions, rendering, mouse events, and more.

Correction: 02:07 Awake and OnEnable are called first, THEN Start - see pinned comment
Correction: 08:35 The physics engine runs 50 times per second by default

Only after all instances of all classes have completed their Awake and OnEnable phases does Unity start calling the Start method. This begins with the first instance of the first class and follows the established order. Remember, OnEnable is intended for logic related to enabling a MonoBehaviour and should not be used to manipulate execution order.
