CARPS, the Computer Assisted Role-Playing Game System, is a tool for playing pen and paper RPGs over the Internet.

CARPS differs from other such systems because CARPS is not a ‘real-time’ system. It suits people who want to log on once or twice a day, take a turn, and then log out again. While OpenRPG could be described as being similar to a chat-room, CARPS is more similar to an email client.

CARPS is an extensible system: game rules are provided by ‘mods’.

CARPS supports these mods by providing:

• Text-mode user interfaces for the players and the dungeon master.

• An easy to use probabilistic API which not only rolls the dice, but can report the probability of various game events occurring.

• Automated static character sheet verification, according to a schema defined in YAML. For example, a game might require your strength to be an integer.

• Support for the semantic validation of character sheets according to game rules. For example, a game might require the sum of character’s attributes to be below a certain maximum value.

• Together the validation features allow a mod writer to encode game rules cleanly, as they do not need to consider the possibility of receiving an invalid sheet.

CARPS has other strengths:

• Anyone can play or host a CARPS game! All you need is an email account.

• As a consequence of this, CARPS is completely decentralized. No-one can stop you using CARPS once you download it.

• CARPS is designed to be secure. Multiple email security options are supported, and all CARPS messages are cryptographically signed to prevent spoofing.

• You can instruct CARPS to use your favourite text editor and terminal emulator.

• CARPS is easy to configure because it includes a wizard.

However, CARPS is new and the following features, which you might take for granted, are not yet supported:

• No GUI

• No support for maps

• No chat - all communication goes through the Game Master.

• Games are currently invite only, at the discretion of the Game Master.

• Security mechanisms are not well audited.

For users:

• ruby 1.9

• rubygems

• openssl

• highline

For developing CARPS, you will also need:

• hoe

• rake

• newgem

• cucumber
