Launch Link for PC: TRON: The I/O Tower in VRChat
VRChat is perhaps the most popular VR destination, with a very large user base and support for not only VR worlds, but fully custom avatars as well. VRChat also works on PC & mobile, so a VR headset is not required.
However, developing in VRChat comes with a high learning curve. VRChat uses the Unity development platform, and Blender is often used as well for worlds & avatars. Coding is done with UdonGraph & UdonSharp (C# for VRChat).
The benefits of using VRChat include a large user base, support on multiple platforms, custom avatars, better graphics, lighting & shading, and complete asset management.
By developing in Unity/Blender, one owns all their development work and code, and can use those assets in other platforms.
