Generic d20

[Cealocanth]

Can someone point me in the direction of a generalized d20 system? I have had multiple requests to run a hard sci-fi game in 5e, but the more I look at it, the more I find that 5e really is meant for fantasy settings and doesn't work balance-wise or mechanics-wise if you remove magic.

I don't think there is one. I mean, there's no such thing as a "generic" class based system, because you still need classes and those immediately de-genericize it in some way.

But you might want to look at Stars Without Number.

Umm... True20, maybe sort of? Been a while since I read it, though.

True20 is the most generic version of d20 available. To the point I think it loses functionality.

The basic classes of d20 modern still have a feel to them, but are also very generic. The equipment, advanced classes, and prestige classes is what changes the feel of that game system.

Aside from d20 Modern (and check out d20 Future, Apocalypse, and Cybertech if you plan on doing SF with that), d20 system rules exist for:

• Star Wars (wotc did two different editions; SWSE was particularly well-received)
• Babylon 5 (by Mongoose)
• Traveller (the so-called T20 rules; very low-powered by modern design standards, but very adaptable to generic SF)
• Stargate (by AEG; uses the Spycraft rules)

You may also want to check out Crafty Games' Spycraft.

Edit: There's also a d20 Star Trek of sorts, in the form of Prime Directive. It's a little too closely tied to ADB's vision of their Star Fleet Universe to be readily portable though.

If you’re looking for D&D style sci-fi you might try Stars Without Number

It's not d20, but you might check out D6 Space (in a free Bundle with other d6 titles here). Free, open source, and a pretty robust system.
