Technical side of things I know little about.
How far has the tech used to make MMOs and the servers the handle them, come along, to allow Fully Voxel MMORPG in the same level of detail of 7 Days To Die, but with the ability to host as many players in the same area as a MMO like World of Warcraft or GW2 minimum?
Of course smaller multiplayer games like 7 Days and Minecraft can do stuff like this. But in MMOs usually masses of players can play in the world simultaneously if they choose to do so. Can a modern day Voxel based MMORPG handle something like that?
if not, how far off you think we are to getting to that point?
