While less well-known than many listed, Greg Stafford was a major figure in the RPG hobby. The creator of Glorantha, a founder of Chaosium, publisher of Runequest, creator of King Arthur Pendragon and much more.
His legacy lives on, with the newly revived Chaosium and their new edition of Runequest.
One of the best writers of fantasy out there. Writing short - by modern standards - and usually standalone novels in a field dominated by doorstops and series she stood out from the crowd.
It’s sad that we’ll see no more of her work, but we can be glad of what we do have.
