- Minecraft - another popular sandbox game platform where users can create and share their own worlds and games.
- VRChat - a virtual reality platform where users can create and explore virtual worlds and avatars.
- Sansar - a virtual reality platform by Linden Lab where users can create virtual experiences and events.
- Decentraland - a blockchain-based virtual reality platform where users can buy land, build scenes and applications, and monetize their creations.
