Traveller, or better yet 2300AD or Hostile for better fit on the setting with the same classic 2d6 rules. Cy_Borg or Stars Without Number for OSR.

Diaspora, Mindjammer, or Nova Praxis if you’re willing to try a more modern system (Fate), but the setting should be pretty close on them, depending on where in the story you want it to be. Diaspora should be a good fit if you want to explore different systems throughout a network of spheres.

All it needs is a name and you’ve got a ready adventure.

Don’t beat yourself over it. 👍

Right, that uses the Fantasy Flight Games' Narrative Dice System (same as WH Fantasy).

Wow. I hadn't heard of a single item in your list except for SLA Industries. Not that surprising considering most are long out of print.

By Jupiter Chronicles do you mean Jovian Chronicles?

Sounds like you’d like Hostile by Zozer Games. They have a solo version too where you control a crew.

Why is it worn out near the top?

Truncated d4 s deal less damage… as caltrops. Also look at that table 🤩

That's right. Arguably the most famous?

Come to think of it, I don't think there ever was a Fate official Star Wars setting. I didn't find it, anyway.

BattleTech! That's the one. Didn't know they made an RPG out of it.

Firefly is an out of print Cortex Plus game by Margaret Weis Productions. It's in the list as well as Serenity (the Cortex Classic game by WEP, isn't IP licensing fun?).

Rifts is a classic, but also a very strange animal. And for some reason I thought Robotech was a minis game (must be confusing with something else).

Star Wars is already listed. I know those are technically different games, but I'm trying to keep the list as concise as possible (grouping the multiple versions of the same setting under one entry). I don't know much about the history of star wars RPG though. How would you summarize it? (WEG d6, d20, Fate)?

Done and thank you!
