So I was recently flipping through some old d20 materials, thinking about all of the interesting tidbits that they had which I haven't (yet) had a chance to actually use in play. That got me thinking about how there's currently a large number of products out there that are add-ons for someone else's RPG system. From supplements DM's Guild supplements to third-party products published under the OGL to stuff on fan-sites, there's a lot out there that takes the "base game" and modifies or adds to it somehow.
Using "variant rules" as a catch-all for material that a third party has written for a given RPG (with "house rules" being stuff that you or your group have invented yourselves, rather than using something someone else made), what variant rules have you used?
