Yes, I'm sure this will be the Unity killer that everyone is waiting for. rolls eyes
Minecraft is owned by Microsoft and has issues (does not run on ARM well and the Java/Bedrock are incompatible)
Roblox is extortion and ugly.
VR Chat is only VR.
Neither scales.
I'm trying my best, here is the status from 2 years back: http://talk.binarytask.com/task?id=5959519327505901449
Now I'm building the voxel world.
This is incorrect. VR chat (and Rec Room) has a non-VR client
VR does not blend well with non VR unless the headset is the camera!
Last time I checked both of those where 1st person not 3rd?
VR blends perfectly fine with non-VR actually, and there are many games that let you play as VR in a non-VR lobby. Check out Paranormal Activity on steam. The game was designed as a normal mouse and keyboard video game, with awkward controls and a strong horror focus, but they added a VR option so if you want, you can feel fully immersed while being chased by evil ghosts and you can pee your pants in fear while your friends stuck with a normal screen are only moderately afraid.
For the two games in question, the non-VR client lets you play homemade games and chat with your friends or strangers who have VR or also happen to play the non-VR version of either. It's literally just a different control method, like using TrackIR in a racing sim.
