I have been playing RPGs and creating content for them for over 35 years - Ever since reading an early Fighting Fantasy gamebook in primary school and deciding to create a story to play through with my brother using the rules. Turns out we were GM and PC before we even heard the terms years later when we were introduced to WFRP.
Years of playing (various versions) of D&D, Shadowrun, GURPS and WFRP has meant the creation of many scenarios, house rules and NPCs, until recently, actually deciding to share content outside of my gaming group.
