GURPS 3rd Edition

GURPS is a "generic, universal" tabletop roleplaying game, which can be used for any setting or genre. The Third Edition rules went out of print in 2004 when the Fourth Edition was published, but many Third Edition sourcebooks have never been updated to the current ruleset. Where no updated sourcebook exists, players can convert Third Edition statistics with the help of the GURPS Update conversion guide. Some sourcebooks are easier to convert than others, though. For the more challenging ones, players can get help on the Steve Jackson Games GURPS Forum.
