Look, I realize the OP posts a lot of stupid shit, but for once, he might be onto something.
As someone who has played D:OS, D:OS2, PoE1, Underrail, AoD, Kingmaker, and Wasteland 2, I have to say, these games are just not very good. I have long been saying that aRPGs are doing a lot more interesting things now than iso RPGs, and fanboys accuse me of preferring aRPGs, but what you have to understand is that I love old school iso RPGs (PST, F1, F2, NetHack/Vulture are some of my all time favorites), and hell, I even enjoyed Divine Divinity way more than the D:OS games.
So what's going on? Why DO these nu-iso RPGs suck really?
Well, if you look at aRPGs during the golden age (late 90s/early 2000s), the pinnacles of the genre were Gothic 1/2, Daggerfall and Morrowind. So if you look at modern aRPGs or similar games, while you may argue whether or not they surpassed the overall greatness of some of those games relative to their era, you can absolutely see them improving in different areas, aside from graphics obviously. There was never an aRPG in the old days with such writing, dialogue, and lore as Witcher 3. There was never an aRPG with such an in-depth combat system and level of historical accuracy as Kingdom Come: Deliverance. There have never been aRPGs with such level of exploration and environmental interactivity as Breath of the Wild. I don't recall an old aRPG with the number of quests and level of C&C as ELEX. Or an old aRPG with the combat/build/weapon depth and challenge of Dark Souls.
So however you might feel about aRPGs as a subgenre, you cannot deny that it has been evolving in the last 20 years, and with games like Cyberpunk, KCD2, ELEX2, BotW2, Elden Ring etc, is set to evolve even further.
Meanwhile, over in iso land, the only novel thing I see is AoD's level of C&C, but given the rest of the game, it feels more like a proof-of-concept for a future game rather than an enjoyable RPG itself. D:OS games tried the whole "combine-elemental-spells" thing but that is such a cheap gimmick that it grows stale extremely fast. Kingmaker tried to expand on NWN2's kingdom expects but failed brutally. The rest of those games were fairly clonish to old classics.
So in my opinion, there has been almost no effective innovation at all in the iso subgenre. Without innovation, which is very important, the only way for these games to be really good is to be all-around good. For example, I am more willing to forgive Witcher 3's terrible exploiration mechanics because what it does with writing and cut-scenes is so new and amazing. But if a similar game comes out in 10 years, I would be much less excited.
However, none of these nu-iso RPGs are actually all-around good, not even close. Even if you claim that D
S games have great combat (something I would personally debate), everyone has to admit their writing is beyond terrible, and the exploration is not really a drawing point either. PoE games are sorta OK-ish all around, but nothing really strikes me as excellent other than maybe pretty graphics. You all know how I feel about Kingmaker already. Underrail has interesting combat and character development, but the writing and exploration are mediocre at best.
Now why is it that aRPGs managed to innovate and create great stuff in the last 20 years, while iso RPGs have not? The answer is not particularly difficult to discern. The industry as a whole has moved on to newer technology and third/first perspective games in large degree, so there is a much higher chance of a full fledged dev studio working on an aRPG rather than an iso game. And the difference shows.
Does that mean iso-RPGs are dead? I don't think so necessarily, but I do think they will be very niche. What needs to happen, imho, is for some well financed studio to decide that it can make a fairly profitable iso-RPG (which I think is theoretically possible, after all if everyone is competing to make the next great aRPGs, it might be cheaper and easier to make something different), and dedicate real resources to it. It would also help if they could zero in on some potential advantages that iso RPGs have over aRPGs: for example, afaik, iso RPGs cost a lot less to make with lower level of detail and possible a lot less voice overs (you don't need to voice over all dialogue in iso games I believe), so one draw could be to use the savings to create a trully massive game, imagine a whole continent with vast jungles, deserts, mountains, plains, etc. Also a ton of (hopefully well written) text which you wouldn't have to voice over, so you could go really deep into politics, lore, intelligent conversations, and so on.
