Keep in mind that there are different schools of thought on what makes a good open world game.

I love exploration and discovery without much guidance, so point-of-interest markers and repetitive copy/paste events (as found in games like Horizon ZD and Witcher 3) bore me. Responsive controls and good user interface are also important to me, so Red Dead Redemption 2 was a miserable experience that quickly drove me away, despite the great environments and character building. Some people consider those games masterpieces, though, so I have to assume their priorities are different from mine.

Subnautica is an excellent example of what appeals to me. Beautiful world, unconfined exploration, excellent soundtrack, a story told through discoveries rather than exposition, multiple ways to accomplish things, and a departure from the usual “kill everything” approach to success. Fair warning: it is a first-person game.

Skyrim shares some of these strengths and can work pretty well in third person with mods like True Directional Movement and TK Dodge RE. Be aware that modding Skyrim is a deep rabbit hole that can quickly become a full time job. One way to solve this is using the Wabbajack tool to semi-automatically install a well-tested mod collection.

Kena: Bridge of Spirits looks like it shares some of its design with Breath of the Wild / Tears of the Kingdom, which is encouraging. I haven’t played it yet.
