So I'm working on the new ship with Smithe and Buddy and Goober.
I'm wondering where you got some of your rolls/checks from? You made it look easy. Like whether someone is Friendly or not. Ideas for Encounters. Where did you get all of that?
TL;DR: Roll up something random, then keep asking "why?" and "how did it come to this?" until you've built The Big Picture as far as you need it to go.
Longer version:
I started out here working with CT rules since that's what I'm familiar with, then dragged in MgT2 where it contributed useful detail.
The reaction roll table is in LBB3 '81 p.27. I get a
lot of mileage out of that.
The starship encounter tables are in LBB2 '81, p. 35.
In both cases I improvised a bit ("ok, what can I bring in as a +/-DM?"). The crowd-scene reaction roll was forced by your narrative (they're hostile and might turn violent, that'd have come from a roll of ___ , roll another task to attempt to thwart violence.) I basically just looked at the encounter table and reverse-engineered the situation (Riotous Mob results from a roll of [1,6] on the Random Person Encounters table).
The ship table is built around LBB2 and only includes ships from there so I treat it as advisory ("it
says Free Trader, but what is there that's
like a Free Trader that best fits this situation?") More to the point, it's an encounter table for a small-ship-universe: seeing a
Broadsword is a Big Freakin' Deal when a
Kinunir is a front-line battlecruiser, but decidedly "meh" when
Azhanti High Lightning is a mildly-obsolete Cruiser. Still a big deal from a player-character perspective of course, but what it means for the situation is vastly different in a big-ship universe. Small ships, a Broadsword can change the balance of power in the ongoing war on Feri. Big ships, it's beefed-up security detail for someplace but not a game-changer.
And that's where I get ideas:
Someone blew up a grav taxi. Bomb? No, too simple. It's a missile. Ok, where did they obtain the missile, and who fired it? Do they have more? Why did they target the player characters, or were they just in the wrong place at the wrong time? How is the local government going to react (overreact...)?
There's a Type A Free Trader. Why is it outbound
right now? (Does a Type A make sense in this system, or does it need J-2? Does where it came from have anything to do with why it's leaving now? Sure, why not?)
There's a Type Y Yacht. Who would own/use one? (Knight or so, Soc 11) Where are they from, and why would they be here? (check Travellermap and the Wiki...)
There's an SDB. That's got our name on it, doesn't it? If it's a 200-tonner out of LBB2 rules, maybe there can be a stand-up battle ending in an escape into Jumpspace. 400Td from LBB5? Can't be quite that simple, or it's going to be a total party kill. Has to be something different...
Almost every star system has a story almost pre-written in the description. Sometimes that's because there was a canon adventure set there, sometimes it's just implied by the world description. Boughene/Regina stood out as a place that didn't have much going on for it except for having a low law level, high tech level, and a class A starport. So being an open trading hub is a big part of its economy. If someone's importing high-tech weapons to Feri, that's where they come from. Then there was the Yacht encounter -- probably owned by a Knight. Boughene has ONE knight, so if they're "on the road" it's got to be for something important... but not something so urgent a J-2 ship is called for.
... and so on.
