RYO is a community-driven project where developers can create and share different game modules that fit within the Dope Wars ecosystem. The game modules are designed to be composable, allowing them to interact with each other and share game states. The project is built on top of the StarkNet L2 roll-up, which offers a cheap and efficient computation environment. The project is open to anyone who wants to participate, and developers can claim the next available number and start writing ideas for a new module.
