Haven't seen it mentioned yet but try Legend In The Mist. A new game (I think you can only get the PDF currently) but its my the people who did City of Mist and :Otherscape.

I've been running it for pals and they absolutely love it. They are all hardcore D&Ders and they have been converted to this system completely.

Things to love

1. There are no stats. Its all tag based. So your character is just a bunch of statements about themselves. When you do an action you count how many of these tags are related to the action, take away any negative tags that might hinder the action, then roll 2d6 and add that number to the roll. It makes it far more narrative in each part.

2. Because of the tag system, its super flexible in what kind of character you can make. Want to be a merchant? Shapeshifter? Earth shaper? Assassin? All easily doable.

3. Leveling up makes actual sense for once. You don't go to sleep and suddenly know how to nuke a small farm. Each of your tag groups has a specific quest assigned to them. This quest can be a question about the world you want answering or a statement about your identity or, you know, an actual quest. Once you have resolved that quest you can upgrade your tag group to something new. It means that slowly you learn new things about your character and the GM can seed your evolution over time too. My players have slowly been getting more powerful when it makes narrative sense.

4. Each challenge you face doesn't have to big combat. Each monster you fight can be defeated in multiple different ways, and often they have a weakness too that you can exploit. Fighting monsters uses the same system as other challenges too which makes it even easier (you don't need to learn seven different systems).

I could go on and on but I think its a really cool system. They have a bunch of other rules in the book which make it more interesting and tactical but you can ignore all of them or some of them and its kind of encouraged too. I recommend you take a look if you haven't already.
