Just a list of things that comes to mind when thinking about what the simulation (game) contains. Do not confuse with the more technical simulation objects (SOBs).
The document will also try to identify different problems and attributes related to the objects.
This document will be used to create further documents to design the base simulation systems. Starting with the document GameObjects.

  • If you think about it - every container is kinda special. Like you can't put liquid in a box. And you can not put a sword in a bottle. So how do we know what you can put in something?

• chat
  • spatial chat - chat by default will only be audible so far
  • oog (out of game) chat - provide a means for players to chat independent of region. There could be a few different channels as well. Maybe this is configurable so that the GMs of the "role playing" shard can turn off all but spatial chat.
  • drunken chat - being inebriated may garble what you say. Would this apply only to spatial chat?
  • chat triggers - there could be object triggers in the game that listen to spatial chat. Examples:
    • PC says a magic phrase and a hidden door opens.
    • PC says a prayer at a holy altar and a demon/angel spawns.
    • NPC hears two PCs chatting and a key word triggers logic that initiates it to try to join the conversation (ala Eliza for MMOs)

        • guilds pay their parent or patron guilds taxes based on a negotiated rate
        • guilds provide points towards their patron guild's guild rank
        • guilds receive a percentage of the guild rank bonus from their patron guild
      • leadership models
        • authoritarian (members can take over by getting their leader killed)
        • democratic (members can vote for their leaders.)
