Metaverse Engines

Unity and Unreal are the most popular cross-platform free game engines. Game engines facilitate the creation of 3d experiences. Although these tools are famous for game development, the need for professional SDKs for 3d application development is beyond the gaming industry. These engines are used by other sectors such as filmmaking, automotive, architecture, military, and construction. 

The flexibility and modularity of the game engine made us to call them as Metaverse Engines because they are the most convenient tools for Metaverse Development. 

We should note that the are also some Frameworks, such as A-frame, which facilitates the creation of 3d virtual reality-based experiences.
