Here, posting it in no particular order because I don't scale to your expectations level.
Divinity: Original Sin 2 - really, it is mixed bag - I'm fond of Larian humour, but some jokes were forced. The main plot, on the other hand, was suprisingly dark and gritty, making it much better then first part (as far as I played, dropped the game soon before ending). Concentration camps for Sourcerers, Void stuff, characters dying left and right. Impressive asset of possiblity to play premade or custom characters. And you can bone lizard as skeleton, that is very important part. (One of few parts of the game that made me laugh openly. This quest is golden as undead) ALSO YOU CAN PLAY AS FUCKING SKELETON. THAT COUNTS, ALL RIGHT?
Witcher 3 - again, mixed bag. The base game has few issues with writing, but generally, it is solid. Missing few important characters (I want Iorveth back, CDP:R. I know you have him) wasn't help either, but to be honest, I really had fun with plot in this game, both side ones or main one (with exception of Ciri choices stuff. You ain't destroying lab of someone cause you are angry HURR DURR). It also managed to make Ciri likeable character, instead of using that retarded bitch from the books. Expansions deserve addtional few lines: Hearts of Stone is absoluty fucking great, entire plot of it takes from all sort of polish folkore tales (Twardowski and such), the choices aren't easy as Olgierd
really fucked up some things, but he is still likeable. Also, Shani and entire ghost wedding sequence. Blood and Wine was beautiful goodbye to the series, taking place in much more coloful area. Great characters (Regis is bro on par of Broche and Talar), more but- I mean, beautiful views, "knightly" atmosphere. I may be a bit biased because I'm fan of the books, but still, expansions raise the writing quality at least by few points.
Age of Decadence - I will get shanked for that one... uh, let me say this - I'm not fan of this game. The reactivity of plot is impressive, but I just refuse to believe it took 11 years to make this game by a team of people. Each route takes max 5-8 hours if you don't include getting shagged by combat system, which is best part of the game for sure. The skill uses were fucking random on most routes, often cutting you from ways to do stuff, entire third act of the game feels like it was rushed as fuck (and considering first two were short ones already...) If anybody from team read that, sorry, but this is what I think. Really, wasted time for me.
Pillars of Eternity - borefest, to be honest. There are few ideas in the game that are done right (attributes - traits interaction in dialogues, few lore elements, Eder), but mostly, it is loredump. Fights are boring enough, but the plot, while having few good hooks, still fails. Expansion is probably best element of the game and I hope that Deadfire will be made based in it, not the vanilla game. (And actually, Tyranny does the choices better, but is still lacking as fuck. Really, joining Overlord in fucking DLC/later patch?)
Icewind Dale - surprisingly, it is very solid. It isn't genius, but for D&D game based on combat, rather then plot and character interaction? Good enough for me. Second one is even better in that department, so I can't really hate either of those. (Vulcano time loop section is pretty fun)
Kingdom Come: Deliverance - ah, Warhorse child. I got to say - it is mixed bag again, but for really different reason then games above. Some characters. for example, are great: Henry, Radzik, Hans (fuck you too bro, you are prick, but bro prick), the rest of the lords are pretty great, while the villain department is severly lacking good characters. Wow, two are gays. Cumans are made OH GOD EVIL BARBARIANS.
Simplicity of the main part (revenge) and mix of the political talk is really great, at least for me. Generally, like it was said, it is blacksmith son turned lord's fighter simulator. I really liked the town patrol quest, the Hans quest at the bathouse is really good too, but absolutly nothing beats Father Godwin stuff. I really liked this one, but it still have large flaws at some points. Also historical stuff: like Sigismund being liked by Hungarians - which was bullshit because they hated the guy for being "outsider" and his lack of care for their business.
Elex - didn't play it yet.
