Maybe it's just me, but open worlds have been quite tiring for quite a while.
Near infinite playing field is a cool concept, but the size is irrelevant if there's nothing to do in the field, what's the point? Having meaningful content evenly accross the stupendously huge field is a challenge. While I could scale a mountain for hours, it begs the question "why?".
I can already scale kilometers deep craters and equally tall mountains in Elite Dangerous, but there's just literally nothing there... well, apart from the occasional crafting material or whatever, but those aren't exclusive to those locations afaik.
The implementation makes all the difference and if the world is just a boring empty place the novelty has already worn off from all the other games in the open world genre that have already done it. That said, games like Minecraft, Valheim, and the latest Legend of Zelda's leave me with hope that open world games can still be fun.
Minecraft, especially when modded makes for a really fun experience exploring a vast world. I could see a game that leans into the adventuring and finding new dungeons and ruins to explore succeeding provided they make the experience of stumbling across them fun.
