When I hear about a new game, I usually read the first sentence or two on Wikipedia. I rule out games described as certain genres or types, like soulslike or online-only multiplayer games. Then, I check reviews on a site like Metacritic. If the critic or user reviews (doesn’t need to be both) are good enough, I add it to a list to play.
I also do this with movies and tv. Obviously, with sequels/series I know a little bit more about the games/movies/shows but I still go in as blind as possible.
Be aware that the Outer Wilds and Outer Worlds are different games
