This is a kind of game engine designed to be a starting point of creating an mmorpg minecraft server. It is built on Minestom, an open source library which allows to build minecraft servers with less overhead using it's multithreading support.
This should have all of the neccesary libraries in order to build an entertaining and interessant server. Players won't need a mod to play (a client side mod could also be created for more indepth gameplay).
