Censorship resistance and data permanence could be one benefit.
You could anonymously make games with all kinds of content, that could not be published on the clearnet. One could possibly gamify a revolution in some countries, for example. The chinese social scoring already looks like a game, so a game developer might make a game that makes satire of that system, and reach huge audience in China.
EDIT:
It’s not how Safe Network can be used for the gaming as it is now, but what kind of gaming can be brought into existence in the Safe Network.
