Haha sorry but the skeuomorph and what I read on the wiki is a little bit too precise for me to understand all the subtleties.
I don't have a problem with that kind of UI BUT it's a very common UI you could find in any games, even in mmorpg. It doesn't translate any personnalities, you don't have any feelings about it. It's very intrusive on the screen if you compare to other games (even to XCom or the new Wasteland 3 to name another modern TB game) but it's functionnal and... that's all.
In some ways old UI was far more invesive. But I felt to projected the feel of world better, then D:OS2 which is... abstract? Gamey?
That is an amazing video, thanks for posting. Monochromatic and skeumorphic was the artstyle the originals went for. Whereas Larian was "gamey" and colorful.
The original was more intrusive in the sense they took more of the screen (and I agree we do not need a U shaped UI), but was cleaner in the playable screen without the projected bars, percentages and lines.
