Though they're a mix of sandstorm/thunderstorm (like in the movie), the Mad Max game from Avalanche.
With Dune I had no problem. One of my favorite books, actually. But Ulysses... oh god. That was a hard book to read (and not finish).
One could accuse Elden Ring of many things, but clunky controls is definitively not one of them.
It's probably one of the best combat systems I've ever played. When you die, you know it's your fault (usually because of greed), not the system cheating you. It's very fair, unlike many others.

Usually when the word "original" is used in the context of media, it means it's a new idea/concept/story, in opposition to an "'adaptation" from another media (like a movie to a videogame, or a book to a movie). This movie is an adaptation.
I'm not criticizing your opinion, as I really like the movie too (including pacing and direction). Only the terminology.
