I’ve put together a hub page for my articles on Ironsworn, a TTRPG built specifically for GM-less solo play.
Intro Article for Ironsworn
Ironsworn is a TTRPG where the story keeps generating itself semi-automatically through its unique Oracle system.
Because of that, it neatly avoids one of the classic solo play problems:
“It’s hard to feel suspense when I already know what’s going to happen next.”
I go into the details in the article below:

Ironsworn actual play journal Series
If you’re wondering things like:
“So what does the story generation actually look like in play?”
“What does a real session of this game feel like?”
—I’ve been writing an ongoing actual play journal series to show exactly that.
At least, I tried to write each episode so it can still be enjoyed on its own, even if you jump in partway through.
So if anything catches your eye, feel free to start wherever you like.

Most of these focus on character builds and mechanics, and I use Python to simulate things like success rates and combat performance.
So if you, too, wish to sink into the swamp… welcome.
