About Dave McAlister

Dave has been roleplaying for over 30 years, having played and/or run most mainstream systems with the espionage genre being an early favourite. So much so that, in 1999, he started Modus Operandi. That same year he joined the Sarbreenar “Living” campaign team as their plotline controller before moving across to the Living Spycraft campaign team (as UK Regional Branch Director) in 2003. 2003 also saw the birth of UK Role Players as well as Dave’s first freelance writing appointment (co-writing World Militaries and consulting on both US Militaries and Battlegrounds, all for Spycraft).

Since then, Dave has concentrated on supporting the UK gaming scene. He has organised and run several small, one-day, events and was the RPG Area Manager for Gen Con UK in 2004. His current favourite systems are Dungeons & Dragons (specifically 5th Edition), Savage Worlds and Cinematic Unisystem. He has a (currently neglected) blog at and runs a D&D 5e SRD website at
