Greetings, folks.  Which RPG system is the one that you've repurposed the most for your games/settings?

For me, it's been Mutants & Masterminds, ever since 1st edition.  At the time of its release, I've been working on de-classing and de-leveling D&D 3.x to be able to use the d20 system in a less restrictive format than that presented in D&D 3.x as well with products compatible with it.  I had purchased d20 Modern on release, hoping that this would help, and while some of its ideas were pretty interesting (such as classes based on the big six), it just didn't hold a candle to Mutants & Masterminds as far as versatility was concerned.  From 1st to 3rd edition, M&M has been the RPG system that I've repurposed the most for my fantasy, sci-fi, martial arts, and horror games for at least a decade.

How about you?

Champions/HERO system for the most part, up until the BBB anyway, there was a large sprinkling of CP2020/Interlock in there as well, which is funny cause I hated Fuzion.

If I get to the point where I need to heavily rework a system, I better already have a group going. As it happens, that has been true every time.

And on systems I have modified or revised: NWOD, WH40KRPG (Only War), The Void, EOTE, Pathfinder in terms of severity. I do so to my tastes (obvs) but primarily to reward player choice and make eccentric/niche builds viable (defo not possible in WH40KRPG or EOTE, for instance -- funny how they're both FFG games...). And then from there, it's case of moving away from the proscribed gameplay of the designers. My Only War game ended up being a seek-and-destroy style game with heavy emphasis on freeform gameplay, some level of non-linearity and a focus on the lives of the soldiers (not just the fighting). Armored Regiment, Maverick colonel, Frontier World (Desert), Scavengers, Poorly Provisioned: it rocked! (if you want, I can PM you the changes made).

If by re-purposed, you mean used to run material intended for another system, then the 4th Ed Hero System.

As a generic system that was the purpose so it wasn't so much re-purposed as much as used to re-purpose other material. Based on your example I think that is the intent of your question.

Spycraft 3rd edition. Tremendously good d20 game system.

Do you mean 2nd? Or did Crafty finally publish it?

Used to play repurposed 1e AD&D (eg for NightLife modern horror, or my friend's WW2 adaptation) back in the day. I guess these days I use those OD&D > Swords & Wizardry > derived games like White Star; but currently I mostly run 5e D&D with repurposed OSR modules and I haven't repurposed a rules system to a really different genre in a long time.

I'm working on repurposing Games Workshop's new Kill Team skirmish game for an "Agents of SHIELD/GI Joe mash-up" themed RPG campaign.

Beat to Quarters/ Duty and Honour. So far I've re-skinned it for Warhammer 40K, Star Trek:ToS and Aliens/Predator. Currently working on hacks for Strontium Dog (Mutie and Honour!) and weird WW2.

Idk if Savage Worlds count because it is meant for most settings/genres.

But Savage Worlds. Once people had a grasp of the system, we had 6 or so campaigns lined up and those are not even published settings.

Fantasy Hero/Champions, in both senses of the question.  I played it straight in multiple settings.  Then I twisted and mangled the heck out of it to do some other things.  Then I got tired of it, but that's another story.

The SAGA Rules System from Dragonlance: Fifth Age. Used it for Ravenloft (even got that conversion published!), Dragon Quest/Warrior, and Final Fantasy I campaigns back in college.

Hard to call the palladium megaversal system repurposed since megaversal is built into the name and all that... But I pretty much use it exclusively for all the things these days.  Only thing it doesnt handle well is netrunning, but lets be honest.  Nobody does netrunning well.

I've used the brilliant basics of Spelljammer gravity and air physics in various contexts for a wide variety of fantasy campaigns.

The Hero Quest board game. My god I've used those pieces for everything.
