The goal of the Fantasy Framework RPG is to provide a simple set of common rules, structure, and tools to enable content developers to build campaigns and adventures. This system is designed to be a basic rule system and object model that can be used in many games, both computer and table-top. There is a standard set of rules and optional rules. The design is a continuation of the REALM MUD System project from 1995.

There are different data types expressed here for properties on objects. They are as follows

• int - integer
• per - percent (really the same as an integer)
• rnd - random spread which evaluates to either an integer or percent depending on usage. It has the form <X,Y,Z> or X d Y + Z, where X is the number of rolls to perform on a dice of Y sides then add Z.
