I just finished esoteric ebb last night and my feelings are pretty similar to yours though I think I skew more negative…
I like the planescape approach to justifying every game mechanic as an objective fact of the setting even if I find the use of dnd stats as your disco elysium cast of inner voices to be somewhat overly constrained.
The comedy often didn’t work for me which makes the moments it did stand out.
The setting itself is inventive and was unexpectedly the part I was most drawn to. Like mystara, it runs with the conceit that the gods are more like very powerful wizards than divine beings, there is a hollow earth that we only hear a few details about, and the world itself is a highly artificial construct. They manage to follow these conceits to some interesting places.
The electoral politics that form the b-plot of the game are perhaps the second greatest weakness in the writing: too imitative of Disco Elysium, too close to the real world. Repeats the same mistake of DE in turning marx and lenin into a single figure responsible for both theory and praxis. Like DE it creates a political framework that contains a curious lacuna compared to the real world. The following ideologies are at the forefront: fascism, capitalism (going from liberal to pure oligarchy), communism (going from ML orthodoxy to social democracy), authoritarian technocracy (wizard fascism) and apolitical (the joke option). Notably absent is any sort of left-libertarianism. No anarchocommunists, no communalists, no syndicalists or platformists. Not even an anprim joke character.
This was fine in DE because politics was mostly channeled through the voice of a zany idiot protagonist but in Esoteric Ebb, the zany idiot is only one of many who is eager to express every possible political stance except the tendencies I named.
Marrying the few political positions available to the framework of dnd stats meant that the political content rang false to me. It was like playing dnd with a well intentioned demsoc.
One way esoteric ebb really differs from both DE and Planescape Torment is in allowing more player agency: the main plot is more than just a wild goose chase and it is possible to ignore the central mystery entirely. DE’s a successfully written visual novel but it is not really much of a role playing game. EE tries to lean more heavily into agential play where your choices actually change a situation instead of letting the player passively receive the story.
