What is the richest gaming brand?

Can you shed some light on the identity of the wealthiest gaming brand in the industry? I'm particularly intrigued to know which company reigns supreme in terms of financial might, considering the immense growth and diversification within the gaming sector. With so many prominent names vying for the top spot, it's fascinating to ponder which brand has managed to accumulate the most significant fortune, potentially through a combination of successful game releases, strategic investments, and perhaps even diversifying into other lucrative areas such as esports or merchandising. It would be insightful to understand the factors contributing to their prosperity and what sets them apart from their competitors.
