TRIS - Server v1.2 Description:

Software that allows traditional pen & paper Role Playing games to be conducted over the Internet.

TRIS is a "client / server" application, and the Games Master controls all aspects of the game from his software, while the players connect to his PC using their clients.
TRIS focuses mainly on atmosphere and storytelling, as opposed to the more numbers oriented approach to gaming found in typical "hack and slash" systems.

The GM server includes features for scenario / story planning, as well as running gaming sessions. TRIS is not locked into any specific RPG system..

The player clients are freely downloadable from the TRIS website (www.trisrpg.com), whereas the GM server is released as a commercial product. A demo version of the server can be found here, as well.
