Again western philosophers, over examining things and wasting resources on fruitless endeavors... Simply put, what is the purpose of communication? The answer is to convey an idea, yet westerners over examining thing beyond reason that they lose the entire purpose, allocating it into multiple reasons.
The purpose of sex - Reproduction
The purpose of games - Entertainment
Western answer:
The Purpose of Sex - Intamcy, procreation, etc...
The purpose of games - Transcendence from reality, entertainment, etc
There is only one true purpose not myriads.
