Welcome to Obsessive Compulsive Design.

This page is the entrance to the wond'rous world of Obsessive Compulsive Design, a one-man band games design outfit based in the deep south-east of England.


OCD’s primary goal is to create, maintain and spread the use of the obSESSION™ Cross-Genre Roleplaying System, a toolkit system providing versatile and customisable rules for role-playing in any genre, era, or possible imagined setting.
