Okay, I am using Mongoose Traveller 2e, but this does not stop me from running the game old-school. Really, the only changes I can see between the original rules and this latest iteration of this fifty year-old game.
Like all my games now it is a paid game. This is actually the second group to solicit me to run a game of Traveller for pay. Cannot say anyone has ever hit me up to run a game of Space Opera or Star Frontiers or the new Alien rpg. I guess Traveller is still topical today. I don't think it is the greatest science fiction ttrpg available, but it sure gets the job done. I have even come to peace with the Third Imperium campaign setting most people ascribe as the actual "game" of Traveller.
Like many other original ttrpgs, there was no setting which came with the game. The game designer assumed you would do what they did and build your own imaginative fictional game world for your players to romp in. And I subscribe to this approach. Can't help myself really. I picked the role of forever GM immediately when I was first exposed to ttrpgs. I wanted to use my own ideas for what a science fiction or fantasy setting looked like. But offering my services as a game referee for pay I have decided what the fuck do I care? If the players want to play in the Third Imperium lets do it! I'm just adding it to my list of challenges I have presented myself with in the last decade to improve my skill as a GM. There is nothing stopping me from carving the Spinward Marches into my version of a sweeping space civilization with its attendant cosmic problems.
This does not mean I have thrown out all my Outer Frontier and Lower Frontier setting information. I've just repurposed the planets for use in the Sword Worlds subsector and called it good. All my factions, npcs, site locations, planetary descriptions; all my nutso ideas will comfortably fit into the published setting.
And it isn't like I can run any of the official Traveller adventures without wholesale changes. Let us be clear about one thing here at the Vanishing Tower. I think the original adventures which were published in the 70s and 80s, with a few exceptions, were unmitigated shit. "What's a great Traveller adventure to use for new players?" is a nauseatingly common question on game forums. "The one you come up with in your head!" Seriously, isn't this why you are taking on the role of Star Master? Because you have cool-ass ideas which demand to see the light of day? If not rethink whether or not you should be taking on the role of a science fiction game master.
I have taken the group through a session zero and it was like 4 hours! To be expected. I wasn't surprised. I think we are going to start at Red Cliff Raceway during a high-level economic summit being held at the popular resort, track, and casino. This is because they ended up with some PCs having a very high Social Standing score. So all the scummy gang members, low-lifes with complicated issues, cheap hustlers and space pirates get tossed aside for the elite and politically connected. Sweet, another change of pace, another challenge.
Oh yeah, another character passed a psionics test. They have potent psionic powers! And three other members of the group have insane gambling skills. Money should not be an object with this crew. So it is all going to be about the intrigue, the espionage running behind the scenes of all the other campaign-changing forces out there pursuing their agendas. I'm seeing this campaign going straight at the big universe-sized threats with the high level connections they have as opposed to small crimes and misdemeanors which lead to bigger conflicts.
To prep for the session I am coming up with various NPCs and matching them with motives you might find at a subsector-sized economic summit. Gamblers, human-trafficking, deadly spy vs. spy action, pleas for peace and prosperity, marginalized peoples clamoring for attention, sabotage, blackmail, political postering... these are some of the elements I see being front and center at Red Cliff Raceway.
