What is the biggest gaming guild?

Could you elaborate on the concept of the "biggest gaming guild" and how it is typically measured? When discussing the largest gaming guilds, are we referring to membership size, financial assets, or perhaps their influence and popularity in the gaming community? Additionally, are there any specific criteria or metrics that are commonly used to determine the ranking of gaming guilds? And furthermore, what are some of the key factors that contribute to a gaming guild's success and growth, enabling them to become one of the largest in the industry? I'm interested in understanding the dynamics and factors that shape the top-tier gaming guilds.
