    GamingDomain Class

    Design:
    This class extends the KnowledgeDomain class and provides a specific implementation for 
    generating responses to gaming-related questions. It adheres to the Single Responsibility 
    Principle (SRP) with its single responsibility of generating gaming-related responses.

    Intended Implementation:
    The generate_response method should generate appropriate responses to gaming-related questions. 
    Depending on the requirements, this could involve a rule-based approach, a trained machine 
    learning model, or some other method of generating responses.

class GamingChain(DestinationChainStrategy):
    """
    GamingChain Class

    Design:
    This class is a specific implementation of the ChainStrategy class.
    It follows the Open/Closed Principle (OCP) because it extends the ChainStrategy class 
    without modifying its behavior. It also adheres to the Dependency Inversion Principle (DIP) as it 
    depends on the abstraction (GamingDomain) rather than a concrete class.

    Intended Implementation:
    The GamingChain class serves as a wrapper around a GamingDomain instance. It implements the run 
    method from the ChainStrategy class, which simply calls the generate_response method of the GamingDomain.
    As such, when the run method is called with a question as input, the GamingChain class will return a 
    response generated by the GamingDomain.
