So I'm thinking of running a Pathfinder (A Roleplaying game based on the dungeons and Dragons 3.5 rules) campaign based upon the Talisman world.

Has anyone else done this?

I've been thinking of coming up with some Cooporative rules for a one off Talisman session and use that gameplay as a vague guideline for the plotline for an RPG campaign.

For that matter has anyone ever created some cooporative rules for Talisman?
