Trying to find some that haven't been talked about yet:

Echo. It's a fantastic experimental infiltration game with an AI that adapts to your way of playing. The setup is very impressive.

Pathologic: one of the three playable characters (the Changeling). It's a bizarre russian game, with an unique world, and messy gameplay. Can't recommend it enough.

Va11 Hall-A: chill bartending game in a cyberpunk setup.

The Blackwell series: comfy, kind of amateurish point and clicks by Wadjet Eye. I like them very much.

Transistor: weirdest game by Supergiant. You play as a redhead with a talking sword. I don't remember much about it except that it was good.

The Fall: (pushing it a little bit, since the protagonist is an AI, but I've always seen here as female.) Criminally underrated puzzle games, disguised as metroidvanias.

Eliza (by Zachtronics): the only visual novel I enjoyed. It's hard to explain, it's about AI, burnout, whether tech dehumanizes people, and solitaire.

Hedon Duology: for something completely different, it's a slightly kinky retroshooter, with amazon Orcs fighting demons.
It may sound a bit dumb, but it's excellent. Huge levels, interesting worldbuilding, and a gameplay based on exploration, puzzles as well as shooting.

There's probably a ton more, but that's all I can think about at the moment.
