An interesting and highly important part of Hytale's succes will be the servers. Servers give the game a long lifetime if executed well. Since Hypixel runs the biggest Minecraft server in the world I'm 100% sure the servers will be able to do everything you want them to do. This may include the ability to do some sort of multiple proxy system so people around the world can enjoy your server with the lowest ping since they can connect to the server closest to their location. This may also include a very well executed "bungeecord" system. Bungeecord on Minecraft is nothing more than a few smart ticks to move you to a different server. It uses the world switching screen which is already in Minecraft to cover up the loading times between servers. With Hytale servers I expect integrated smooth and fast server switching. Anyways those are just my speculations. I'd love to hear what you guys think!
