Hey Matt, great question.
As for whether games are eligible under this framework, the recommended metrics are designed to help delegates make informed decisions. Projects applying for incentives around edge-cases that may not stand in a certain TVL bracket, such as gaming, can still apply with their justification for a grant and delegates will ultimately make a decision on each application.
That said, this program is designed for applications that are currently deployed on the Arbitrum network.
If your project has not deployed, I recommend exploring some of the other grants programs including Questbook’s, which has a specific category for gaming itself:
Hope that clarifies…
