These are the four playable options available in The Saga of Ryzom, developer Nevrax' imaginative persistent state title, which is set to enter commercial service tomorrow in the European market and next week in North America. Building on these inventive elements, the game also incorporates many other features of probable interest. For instance, it has a story aspect designed to permit the narrative on each server to diverge, taking its own path and creating its individual saga. Another is a flexible skill-based character advancement system. A third is an unusual modular scheme that allows players to join various components in a building block-like manner so as to create spells and special attacks that are, in effect, customized according to their particular personal preferences. To improve our understanding of this highly intriguing facet, we turned to team leader David Cohen Corval.
