The TWO Big ways of making games in Unity!

Unity game development supports two valid approaches: using MonoBehaviour for Unity-specific components attached to GameObjects, or using plain C# classes without MonoBehaviour. The plain C# approach gives developers manual control over update loops by passing delta time explicitly, making it especially useful for tycoon and management games where time manipulation (speed up/slow down) is needed. A single MonoBehaviour can manage a list of plain C# objects and call their update methods manually, providing fine-grained control over game logic execution.
