Can I get a clarification?

Is it the Third Imperium that you dislike or the 2d6/TL progression of the Core Rules?


I could live with Traveller's tech assumptions. I don't like antigravity or M-drives, but I can live with them. I'm not sure what the official interpretation is of a planet having significantly low tech while engaging in interstellar trade… but never mind, I can cope.

I dislike the 2D starmaps, but they won't matter for this undertaking. I dislike the dodgy and dated astronomy and planetology, but I reckon that EDG wouldn't put up with them either and that you will be using something much more realistic.

Things that really turn me off are (1) the way the Imperium works (2) the Precursors and the prehistoric spreading of humans to the stars, (3) Vilani culture, and (4) most of Traveller aliens.

Quote:
I don't see how linking it to the Imperium would help in any way, but there are lots of questions like "How do they get to orbit?" or "How long is the trip to the Asteroid Belt?" that are driven by the assumed technology and are a little harder to make completely rules neutral.


I'm okay with Traveller tech. I'd prefer something less retrofuturistic: a possible future of now instead of the 1950s, but I'm not really fussed.

Quote:
I'll be happy to make it as neutral as you can come up with answers for basic technology questions.
(I am a gearhead, so I am happy to throw out some basic data like maximum Gees and total delta V and go as Hard Science or Space Opera as anyone can make a case that we should.)

I really don't know how popular Traveller is among interstellar SF games, so I can't make an appeal to breadth of market. I'd just prefer to work on something that was useful with a bit of straightforward adaptation in Diaspora, The Thousand Suns, Stars Without Number, Starblazers Adventures, etc.

Is this the sort of thing you're thinking of? http://www.sfrpg-discussion.net/phpBB3/viewtopic.php?f=30&t=1498?

What about this? http://www.sfrpg-discussion.net/phpBB3/viewtopic.php?f=30&t=1493

So do we want something like this? (EDG modified Traveller Worldgen 2.33)

Code:

Or this? (EDG modified 2300AD worldgen. Ugh, I don't like the close superjovians... this doesn't account for gas giants tossing out planets as they form).

Now that I think about it, I seem to recall that planets in the OTU tended to have very small populations.

Most of them. 7 out of 12 had less than a million inhabitants, 1 out of 12 had a billion or more, the other four were somewhere in between.

The populations are all over the place in the OTU, and of course it doesn't tally with the distribution that results from the CT worldgen.
The realistic UWP worldgen that I came up with shifts it more noticeably towards the lower end, since I link it to habitability and habitable worlds are rarer in my version of the worldgen.

Is there a plot or two in there? If a planet is hostile to life, so that everyone has to live in domes with an absolute maximum population, then there are going to be a whole raft of social controls on family size and visitor influx. You could do all sorts of things with that from tragic to silly. For instance...

1. Dome Alpha is hosting the World Intergalactic Cup. 500,000 football fans have descended on the place. The government is making light of it, but life support is creaking at the seams...

2. The PCs (or passengers on their ship) bring their dog to Asteroid Beta. While taking said dog for a walk round the docks, they get assaulted by an irate citizen screaming "Your dog is breathing my baby's oxygen!". The baby doesn't exist yet - the citizen is on the waiting list to be a father...

Or if a planet has a really low, population, perhaps whole continents are empty? Some rich kids hire the PCs to take them to an empty continent for the ultimate party - away from parents, the law and complaining neighbours. But also far away from hospitals, lifeguards, fire engines, etc. Can the PCs keep these drunken idiots alive long enough to collect their fee?
