There are many in the community that are making plans to create MMORPG/MMO servers on hytale, I can see some already have sample models made in blockbench. However what many don't consider is the AI behavior in Hytale, we are still not sure whether editing AI behavior is easy or not. My suggestion is to start learning basic AI before the game releases, that way you can be ahead in creating custom mobs with advanced AI behavior.
