The Gamemaster can create and keep track of all in-game information. She can also customize game assets and user interface elements to accommodate house rules.
During the sessions of a role-playing campaign, the Gamemaster constantly needs to update the setting. With Fantasy Grounds the pieces, once set up, stay in place neatly and the Gamemaster can be at ease with the book-keeping and concentrate in orchestrating the game. The "folders" where the in-game information is stored are carefully designed for role-playing use.
The technology built for Fantasy Grounds admits the inclusion of customized and entirely custom-built rulesets. By modifying the database source files a devoted roleplayer can mold the software to accommodate almost any game system. Support for these low-level customizing features can be obtained from the Fantasy Grounds web site and the accompanying message boards.
