Game Ontology
The Game Ontology Project (GOP) is a framework for describing, analyzing and studying games. It is a hierarchy of concepts abstracted from an analysis of many specific games. GOP borrows concepts and methods from prototype theory as well as grounded theory to achieve a framework that is always growing and changing as new games are analyzed or particular research questions are explored.
The Game Ontology Projects approach is to develop a game ontology that identifies the important structural elements of games and the relationships between them, organizing them hierarchically. The use of the term ontology is borrowed from computer science, and refers to the identification and (oftentimes formal) description of entities within a domain. Often, the elements are derived from common game terminology (e.g. level and boss) and then refined by both by abstracting more general concepts and by identifying more precise or specific concepts. An ontology is different than a game taxonomy in that, rather than organizing games by their characteristics or elements, it is the elements themselves that are organized.
RPGnet Wiki
The main purpose of this Wiki is to provide a space for various community RPG projects. This will include: people creating their own game systems; people communally creating game settings; and people creating collections of resources for their favorite games. Likely, other things will come up too.
This Wiki is explicitly not meant to replace any of the other functions of RPGnet. Thus it's not a place for general discussion, reviews, or articles or columns.
