Doesn’t seem like many games at all have achieved this. If any. Seems like an extremely difficult problem to try and shard a multi player game on to multiple machines while still being able to interact with everyone.
What makes games like minecraft great is the gameplay that naturally emerges from player interaction. This aspect of voxel engines should be actively pushed to the absolute limit.
People in the gaming sector tend to apply new tech to improve old overdone gameplay (like making games more hd) instead of enabling previously impossible experiences.
