The best rpg games like Fable are Fable II, Kingdom Come: Deliverance II and The Outer Worlds. Below are 11, each with the reason it is here — and, at the end, what filtering to rpg costs you.
Filtering to RPG means you want progression — a character to build or a party to grow — layered on top of whatever else you liked.
What you get: A reason to keep going after the novelty wears off. RPGs are the genre that reliably converts hours into feeling more capable.
What made Fable worth playing in the first place is covered on the full list. This page is the rpg part of that answer, and only the rpg part.
The one that got closest to the pitch — a dog, a family, and a town you own.
A world that reacts to your reputation, played completely straight.
Reputation with factions as a real mechanic, and much funnier than it looks.
The other great British-feeling fantasy RPG, and far deeper tactically.
BioWare's martial-arts RPG, short and unusual.
First-person fantasy RPG built around factions and choice.
Consequence-heavy RPG where your reputation is the whole system.
Mid-budget RPG with faction reputation that genuinely changes quests.
If what you actually wanted was the marrying, the house and the life.
Immersive-sim RPG where consequences follow you across stories.
A place that remembers what you did, over twenty-five years of its life.
Immediacy. Almost every RPG asks for a slow first few hours, and the systems that make hour forty good are the same ones that make hour one a menu.
Specifically, these are strong answers for Fable that are not rpg games, so they are not on this page:
The full list is on games like Fable — 12 picks, no genre filter.
Fable II. The one that got closest to the pitch — a dog, a family, and a town you own.
No. Fable released on the Microsoft Xbox, but a recommendation is only useful if you can play it, so the picks above span platforms and eras. What they share is the genre and the reason.
Whether the stats are the point. In an RPG the build decides what you can do; in an action game with stats the build only decides how fast you do it.
No. The picks below span turn-based, real-time and action RPGs, and each one says which it is.
By hand. Each pick was written for the full Fable list first, on what the game actually does, and this page is the part of that list that is rpg — never a genre tag lookup, which is how "best racing games like Super Mario 64" used to be a page on this site.
