The dark moon version is a MOD~ made by the player himself ~ of course, the equipment and tasks inside are not the same, and the map has also been modified. Dark Moon's weapons and equipment have changed the most, including 12 constellation, golden garments and CS equipment (and guns! )
If you are tired of playing Diablo II, it's not bad to play Dark Moon World. I heard that Dark Moon World has its own server, which can connect to Battle.net and play with other players!
