This is very much a matter of personal taste. As such, I'll write a bit about what I like, so you can estimate how much your taste overlaps with mine:
My favourite game is Planescape: Torment (alonside Brian Reynolds' Alpha Centauri and Homeworld).
I like a good story and good writing in many of my games (though I won't shy away from Factorio, KSP or Minecraft). I also like the Numenera setting and mechanics, and have roleplayed a tiny bit IRL using it.

Tides of Numenera presents itself as a spiritual successor of Planescape: Torment. I feel that it fails short of its predecesor in many ways, chiefly in the quality of its writing and that of its story.
Let's pause here for a moment. I feel the writing in Planescape: Torment is the best in any video game I've seen. Torment: Tides[...] has merely good writing, sometimes excellent, but it falls short of Planescape: Torment.
The story itself is less interesting - I simply care less about the main conflict - although the sidequests are fun. The characters are less memorable than those in Planescape. But: it's hard to equal Chris Avellone's writing and FemSheps's (I mean, Jennifer Hale's) voice acting.

Compared to the Best Game Ever, it falls short on every account (except combat mechanics, which are improved).
Is it a good and fun game on its own? Yes. Engaging, enjoyable and relatively well-polished on release. 8.5/10.
---
As a final note: the game feels like a game made by fans. Something akin to Pandora and Civ: Beyond Earth compared to Alpha Centauri. And, well, fellow creators the creator seeks, not fans.
Saying the above in another way: it feels like the game tries to recapture Planescape: Torment instead of trying to stand on its own. Is it a good idea? Never. Is it what I funded on kickstarter, and what was promised to me? Yes it is. Whose fault is it? Mine.
