It may be that you're underselling yourself by calling it gamification.
For myself, and potentially new adoptees of Hive, I saw Hive Buzz as being a learning pathway to understanding the ecosystem and an incentive for completing various badges in order to learn about that particular aspect of Hive. Having the ability to see the whole list of achievements that I haven't yet completed motivates me to keep exploring and makes me aware of the possibilities available. 👍
