Traveller uses a
2d6 dice system where characters add their
relevant characteristic and skill levels, with various possible
target numbers and situational modifiers. It also has a notion of
“task chains”, where one roll gives a bonus or a penalty to
another. This post runs through all these variations, with lots of
The Fog-spawn (or Thing in the Fog) is an other-dimensional creature from the Masks of Nyarlathotep campaign for Call of Cthulhu. If you’re a player in that campaign, turn back now: there will be spoilers!
Here’s how to learn a new RPG system. Or at least, how I learn a new RPG system. In brief: skim through the book, practice making some characters, read the book more carefully, run a one-shot, make cheatsheets, and then run that campaign.
Campaigns can be huge games which last years. Players might come and go. People’s tastes might change. What you decided the campaign would be about one, two, or more years ago might not be what the players want any more. So, hold a mid-campaign check-in to ask about how everyone is finding the game and whether anything needs to change.
1d12 + 1d8 table is commonly used for
random encounters, because it gives a nonuniform distribution where
some outcomes are more likely than others. But why stick to that?
By rolling one of the dice with advantage or disadvantage, you get
a very different distribution, and can make one table work in many
This is a homebrew skill I gave one of my Masks of Nyarlathotep players after they decided to become friendly with a time-traveller. 10% chance of answering a plot-relevant question, and immediate recognition of key NPCs.
A lot of GMs advise rolling behind a screen, so you can fudge rolls when you get a result which would be bad for the story. I think that at best fudging is unnecessary, and can be remedied by being more thoughtful about what rolls you ask for (and I go in to how I think about rolls), and at worst cheating, where you’re explicitly ignoring the rules of the game.
This is a starter adventure I wrote and ran for my Troika! group. It’s in two parts: first you have to get to the manse, by travelling through Emmy Allen’s Gardens of Ynn, then you have to search the manse for the magical artefact the party’s patron has sent them to find. Don’t worry, Mazirian is supposed to be long dead… but is he?
Today I ran my first session of Troika!, a very weird Book of the New Sun / Dying Earth / Discworld style game. We had a lot of fun, it’s pretty rules light, and we’ll probably be playing it again some time.
Knock! is a recently kickstarted zine full of goodness from the OSR blogosphere. It’s wonderfully designed, and crammed with information. There’s a nice mix of stuff which is immediately useful (like Just Use Bears, or the Dungeon Checklist), and some more thought-provoking articles too. Plus some great art. I recommend it, and am looking forward to issue #2!
Call of Cthulhu uses a roll-under percentile dice system. It also has a notion of task difficulty and situational modifiers, and a way for two characters to directly compete. This post runs through all these variations, with lots of graphs, and gives my rules for deciding what sort of roll to make when.
