The only thing I would classify as a good D20 'Sci-Fi' and it's a HIGHLY DEBATABLE point of contention, is Mutants and Masterminds 3e.  Which yes, is mostly superheroes, but there have been settings in the Comic world that have been purely pseudo-science and cybernetic and robotic, which is why I list it.  BUT I'll also freely concede that it may not be what the OP wants in terms of Science Fiction gaming.

But that's the only thing I can think of that's decent, D20 and CAN have Sci-Fi.  Again, personal opinion.

If you're going to include M+M then you might as well add True20 to the mix. The original book had Lux Aeternum, Mecha vs Kaiju and Borrowed Time as settings.

Is it still being sold?  I thought it was discontinued.  I stand corrected, and your suggestions, Krimson, is more in the spirit of the thread.

I enjoyed True20 quite a bit, and the fact it was more or less compatible with Mutants and Masterminds 2e was a bonus. I could use the Bestiary in M+M games and drop in monsters mostly without changing a thing. I liked the Lux Aeternum setting as well. It would be nice to see that updated for Green Ronin's AGE system or something.

Speaking of AGE, if that counts then I would also include Titansgrave.

Quote from: Nihilistic Mind;900911D20 Star Wars Core Revised? Of course, it's Star Wars, but if I had to run a (non-Star Wars) Sci Fi game with D20... it would probably be with the aforementioned book.

I've often thought that the D20 Star Wars game would make a great generic sci-fi setting. I think you could even run a cyberpunk setting with it. I'd pull out the Force. Or change it to a 'psionics' system. Under Pathfinder I'd use Dreamscarred Press's psionic rules.

Quote from: Omega;900934Dragonstar was one of the early tries at a d20 space setting. Think it came out before d20 Modern?

Mecha Crusade was another interesting one from Polyhedron.

d20 Future was totally unimpressed with.

Dragonstar was great. I remember some fan tried to get a Pathfinder version off the ground. The generic D20 sci-fantasy books Arsenal and Factory are must haves if you are doing a D20 setting.

I once did something like that for d20 Modern, though I think I used the system from Saga. It's been a few years but here is the link.

I just remembered another game that might be useful, Dawning Star: Helios Rising. Used copies seem to be pricey though. I just saw that there is a PDF available for $13.

I'd consider that sci-fi. Will check it out the next time I'm at the store. I figured it used its own system.

I played quite a bit of DragonStar. But I'd say the most consistent rules wise would be Stars Without Numbers.

I want to like Starfinder, I really do. And I hope it sells well and is a nice system. But if it has the modifier soup that 3.X games are known for, I might hold off on buying more than a pdf copy.

What flavor of scifi?

If you want D&D in space, check out Hulks & Horrors.

If you want D&D's system in space, I highly recommend Stars Without Number.

I'm actually one of the few people who liked D20 Fading Suns, but it was a missed opportunity on many levels.

Hulks & Horrors is great. Vastly under-rated book.

Star Wars Saga Edition is my favorite "d20 sci-fi system" by far.

The Force was strong with that one, even if they have a few hiccups here and there.

What are the main differences between Saga edition and D20 SW Revised? I've only ever played D20 SW revised, and always heard good things about Saga edition but never looked into it.

There are a lot of differences.

The skill system was cleaned up (less skills).

Classes were condensed (Soldier, Noble, Scout, Jedi, Scoundrel).

Combat system was revised and streamlined quite a bit.

The Force rules were completely reworked to emulate the genre better than ever. The use of vitality (health) to use Force Powers was always nonsensical to me given what we see in the movies. Saga ditched that entirely.

The talent trees were a cool addition letting one customize their character beyond just the choice of skills, feats, and class abilities.

Most of the supplements were top notch and it covered all "eras" of Star Wars play.

Most importantly, Jedi did not really outdo PCs of other classes by default. A level 12 Soldier for example is still very much a threat to a level 12 Jedi.

All PCs can cut down your flunkies and riff raff like the chaff that they are, which is very much in tune with the movies. With a few minor house rules, this can even be done without a lot of bookkeeping.

I ran two good solid mini-campaigns with Saga Edition and the games were among the best I've experienced. Probably worthy of film cans.
