Size Matters, and Subsector Trial Run 2

The conclusion of the first trial run was that worlds were too big, the change I made was too drastic. So I sat down and did a few more 10k runs. This is a graph of the relevant world types – I consider something like “rich” to be too poorly defined to begin with.

Note that I added “Se” (Super-Earth, size 10+) and “Sm” (Small, size 2-) for this exercise.


I hope it’s not too small to read. Anyway, the graph shows 3d6-3, 3d6-4 and 3d6-5 compared to 2d6-2 when rolling for world size.

Obviously Super-Earths dramatically decrease and small worlds increase during that sequence. Fluid Ocean worlds are also directly tied to large worlds, and Vacuum worlds to small worlds.

3d6-5 would result in more asteroids than 2d6-2. Again, a no-brainer, but since I wanted to reduce smaller worlds not increase them, this seems like a poor fit solely on this criteria.

3d6-4 seems like a good compromise choice for my purpose based on this graph, so I’ll use that.

Tech Level

I haven’t really been able to make TL behave nicer, and I didn’t want to add a lot of filters. I can still do that in the future, but I have another plan.

Trial Run 2 Subsector


Many garden worlds in this one. I like how there again seems to be a cluster – marked by red communications links – of “developed” worlds contrasting with the “frontier” of the rest of the sector.

World #808 has a population of B, “hundreds of billions” and  must be the undisputed superpower of this subsector. Tech Level is again generally fairly low, considering I was aiming for a nominal 13 on “core” worlds, but it is a fairly decent mix if one looks at it as a pure Traveller-like premise.
