Last night, I ran a one shot of Mörk Borg, the OSR dark metal fantasy RPG.
The best thing about Mörk Borg, and what more RPGs should aim for, is providing all of the little tools that make like easier for GMs
The character generators, the dungeon generators, the free Foundry VTT plugin, and of course, all of the third party stuff they encourage. I was able to throw together a decent little tomb crawl from scratch in about an hour.
If you make a RPG easy to for me to run, I’m a lot more likely to run it. I’m not even talking about expensive things – fillable character sheets, lots of pregens, simple adventure generators would improve almost any game.
As I start to design my own stuff, I’m trying to keep this idea in mind.
