I need to consider the context. Is the user a consumer looking to activate the game? A business trying to distribute it? Maybe they're a developer who created the game and need to manage keys? Since the query is about "develop a piece," perhaps they want a marketing piece, a how-to guide, or a sales page.
In summary, the piece should guide users to legitimate sources for obtaining activation keys, explain the activation process, and offer assistance for common issues. Also, highlight the purpose of the game and John Deere's commitment to education and sustainability.
If the user is a seller or marketer, maybe suggest using the activation key as part of a promotional strategy, offering keys as part of a package, or for enterprise clients.
