Well, since that I am satisfied with the maps and items for now (in reality, the current system is at the most primitive stage of development, because I still need to clarify some things in the design of the game to ensure that where I am headed is the right path) I will proceed to integrate NPCs.
Now, the Forge Editor will also be touched, but I am not sure to what extent. I am thinking about approaching it differently as I will need a solid tool-set to add game content without having to write the XML files one-by-one.
