I've release a new solo/coop TTRPG about mapping a journey through the Milky Way with your immortal and unusual crew. It's inspired by the High Frontier Interstellar board game I helped develop but goes much, much further: to the galactic core and beyond! half-apress.itch.io/a-lot-of-zer...

I checked and yes, Kojima predicted this in 2008

Engineers disease is the belief that because you have expert knowledge in one field, you are an expert on everything

I think they’re a lot more prone to engineers disease which is a well established risk factors for extremism

Yeah 3D6 is just a crazy curve.

Can you intuitively tell me where 57 cm falls on a 1 m long ruler without reading the numbers?
andrewdoull.bsky.social
And to answer the obvious question, Sixty Years in Space is a 1D6 roll under system that masquerades as something much more complex so you feel like you’re getting your moneys worth.

Thinking about Apocalypse World dice curves must be in the water tonight.

Good morning! I have had a couple of people tell me Ex Ten shouldn't use 2d10 because it breaks the PBTA probability curve. They could not be more wrong and I am going explain why, because it's the end of my campaign and I need something to keep me sane, ok?

Strap in.

Thanks. It’s great to see a nuanced view on this.

Anyway, the answer to your question is "there's nothing wrong with using 1d20". I actually think the significance of die choice is massively overplayed. My whole rantthread was really a response to someone saying my dice mechanic was borked, but TBH I don't think the choice is that significant.
andrewdoull.bsky.social
What’s wrong with using 1D20? It’s a lot more intuitive for modifiers.
andrewdoull.bsky.social
Flexibility how? Reducing the standard deviation of a roll only matters if you use the numerical output - not for a binary pass/fail. And if you’re using the numerical output, I’d argue you could just use a fixed value in almost every instance eg hit points.
andrewdoull.bsky.social
With a 1D20 system you’re comparing two numbers.
andrewdoull.bsky.social
You’ve already made two numeric errors defending 2D6 in the space of this thread, if you want a real world example of how hard it is to understand.
andrewdoull.bsky.social
You’re still adding numbers together.
andrewdoull.bsky.social
Designing a game where the players have to understand a 2D6 probability curve is a much greater failure.

Fight me

In summary, 1D20 is better than any 2Dn system for making probabilities intuitive to the players.

18-20 is also a 1 in 6 chance.
andrewdoull.bsky.social
If you told your players they’d have to roll 18+ to succeed on a D20 for every roll they’d rebel and yet that’s what Apocalypse World does.

(10-17 is a mixed success. And you wonder why players get “complication fatigue”).
andrewdoull.bsky.social
Regular reminder that rolling 12 on 2D6 is almost twice as unlikely as rolling natural 20.
andrewdoull.bsky.social
So what mechanic is it? Bad board buff?
andrewdoull.bsky.social
I guess the better fix is to let Falcon bounce 0 cost cards. That’d make Hammer decks slightly better.
andrewdoull.bsky.social
You’re playing a bounce deck. You’re already having to play around Killmonger.
