Software (for maps, char sheets, etc)

MapTool

An online, multiuser virtual tabletop for roleplaying games. Players create and explore detailed, infinitely scrollable maps, place and manage tokens, track properties, health, status, and initiative, and communicate through an integrated chat function. Unused features can be hidden, while maps can be displayed on a large screen or projector. The system is game-system agnostic, with optional support for features such as hex grids and square templates.
