A Unity Editor , a Marketplace (Young Parrot NFT Marketplace), and the Game itself. 3D City offers a unique way to create, assemble, and share 3D unity models. We empower Creators with intuitive, powerful content creation tools. You can make your own 3D unity objects, animate them, and publish/sell them in Young Parrot NFT marketplace. Unity is the 3D tool that allows anyone to create or import their own 3d objects, work on them, and effortlessly export them to the marketplace where users can turn them into limited BRC-20 tokens called ASSETS. ASSETS are virtual tokens for digital scarcity, security and authenticity. They are unique/limited as well as distinct and indivisible. Blockchain allows creators to have true ownership and thanks to this technology we, in our capacity as developers, can finally reward players for their time and the hard work they put into content creation, allowing them to monetize and freely trade their ASSETS. Our ASSET smart contract allows content to become the new platform, creating a new paradigm. This is because they offer multiple uses and are not confined to a single game. This "second-layer programmability" gives any developer the power to bring a lasting and ever-growing value to the ASSETS, which can be shared cross-games, cross-platforms and cross-chains. The Marketplace is the trading environment for ASSETS, where they can be given away for free or sold to other PLAYERS. The Game is the overall game system where playable experiences can be enjoyed and shared. In the Game, not only can creators profit from their creations, players can play-to-earn by collecting resources, rewards, and tokens.
