D&D 4E Game System

The Dungeons and Dragons 4th Edition "system" is the common term used by gamers for the latest iteration of the d20 system.

Although Wizards of the Coast still puts a d20 logo (different from all the 3.x books - this one is squat and yellow), the system isn't usually referred to as d20 on the Wizards website. They tend to use the term "4e Game System" and have produced a license called the GSL 4e - Gaming System License 4th Edition. The WotC website also makes reference to a "d20 GSL" for non-fantasy based games.

Until we have better classification as to what this system is called, we are using this system to describe:

The core system used by Dungeons & Dragons 4th Edition
The core system used by third party products that are compatible with D&D 4th Edition.

If and when Wizards formally breaks off "d20 GSL" for non-fantasy based games, we will add that as a system and remove associated references (in the form of alternate names) to the "d20 GSL" here.
