[Mission Request v2] Develop Onchain Social Games that Attract Builders to Optimism

[system]

A North Star Metric has been added at the bottom of this Mission Request in an effort to enable the Collective to make data-driven decisions. By using a single metric for each Mission Request, the Collective is better able to evaluate the performance of all the Season 6 missions in a standardized manner, which will be critical when the Collective makes decisions about Intents, budgets, or other critical components of governance.
