Saw this tweet today and one of the first answers that sprung to mind was Ben Robbins’s West Marches post. While obviously not germane to that conversation, Ben’s post (and his follow-ups), to my mind, sent a shockwave through the ttrpg world. Not only did it launch a thousand West Marches knockoffs, you can see its influence in the OSR and the reemergence of sandbox play.
I’m curious: What are the other foundational works of internet writing about ttrpgs, in your eyes? Blog posts, forum posts, etc. but specific pieces, not people, games, or full blogs.
EDITED TO ADD: Please include a link if possible! Hopefully this can be useful as library of important online RPG writing.
