Having just finished the Horizon Burning Shore DLC and the Sand novels, been itching for more in that kind of vein.
Ideally something with a futuristic setting, and you are discovering either the lost knowledge of the past or investigating some precursor races. Bonus if there is some mystery elements to discover what happened to us/precursors/the ancients before. The Horizon games were perfect for this, but even Mass Effect had some of this with their precursor race investigation. I liked Outer Wilds for similar reasons too.
Doesn't necessarily have to be a character action game, open to most genres.
