Turn Watcher is a tool based on Dungeons & Dragons rules. It is used to track the initiative of your players and monsters. It includes an option to roll initiative on every round, roll will, listen, and spot, and it has a status column that shows you the current status of your players. When you enter a player or monster, you also enter all of its modifiers, so the computer can take care of rolling all the dice for you. Still want to roll initiative? You can simply order the characters with the Move Up and Move Down options.
PCGen is a Java (1.5+) -based character generator aimed at supporting OGL role playing games like those based upon the SRD, RSRD, and MSRD (such as Dungeons and Dragons). It is highly configurable by the users, allowing the Game Master to add or remove races, classes, feats, etc., and to implement house rules such as differing class or race restrictions. Level advancement is also supported, with configurable progressions of feats, skills and ability score bonuses. For "at the table" support, PCGen offers a set of GM plugins. Further options allow the user to produce a customized character sheet, which can then be viewed in, or printed from, the user's WWW browser. It can also produce a "party" sheet with the information needed by the GM.
