I could see this being interesting in treating game elements as React components and using that level of abstraction.

E.g. imagine a Snapchat "lens" type experience (one screen with little fun mini game experiences) that the user can easily add or remove characters or entire chunks of the "game" (turn on/off raining objects the character can interact with, configure, etc).

Could also make it easier for LLMs to generate unique simple game experiences with these building block "components" vs having to build everything from scratch.
