Looking to recreate the feel of Firefly, The Outer Worlds, The Expanse, or similar, in a ttrpg that is somewhat leaning to the hard sci fi side. Any thoughts?
I've been poking Traveller but it's hard to tell what the definitive versions are. Also Stars Without Number looks interesting.
I'm particularly looking for ship based stuff -- where the ship is statted and you can have ship to ship combat.
Stars Without Number looks interesting -- been poking the free basic ruleset PDF. I don't like the focus on psionics and teleportation and other sci fi tropes that are not as hard. If one were to run a zero-psi game, would the system still work?
Which "edition" of traveller have you used, and how do you even pick an edition? Are there inter-edition and inter-publisher compatibility?
Psionics is the reason there is FTL in the default setting, and also why it's a post-apocalyptic setting. You don't need psionics to travel, like in 40k, but I reckon removing psionics from the setting is taking away some of its flavor.
But from a gameplay point of view, I really don't think it's a problem. You could probably search the Reddit sub for Kevin's word on it, but from what I recall, it's a non issue, because it's OSR and the game isn't "calibrated" for a particular party, like say DnD3.5.
You could always leave psionics in the background, something dreadful and not known to the public, like in Babylon 5 or Firefly. Even in SWN itself, like I said, psionics is the reason for the whole mess the universe is in, so they're definitely not omnipresent, and more likely to be a trouble magnet, if present in the party.
