A bit of a hard choice, but here goes, in no particular order-
1. Darkest Dungeon.
It's just a satisfying game. At the start it seems unforgiving- and it is, quite. But there's a difference between unforgiving and hard. You get punished hard if you commit mistakes, but it has a satisfying learning curve; and once you spot the common mistakes and avoid them, learn how to do good team compositions, and all that jazz, it actually becomes quite a chill game. Plus, the aesthetic is impeccable.
2. DOOM Eternal.
There isn't much to say on this one. Unrelentingly tearing through hordes of demons as an unstoppable force of reckoning with heavy metal in the background is just one of the most fun experiences in gaming. Praised be Mick Gordon.
3. Blasphemous 1 & 2.
I can't decide which of the two I like more, but both are absolutely impeccable. The art direction is by far my favorite of any game, and the Spanish voice acting is chef's kiss; only game I ever play in Spanish despite being a native speaker. And the gameplay is just basic soulslike metroidvania fun, with some neat boss and area design. Though the first one definitely leans more into the soulslike side and less metroidvania, while the second is the other way around; that's a matter of taste.
4. Middle-earth: Shadow of War.
Simply one of the best games of all time. I'm a LOTR nerd and I can recite FinwΓ«'s family tree from memory, so the fanfic-level lore in that game is certainly yikes, and the art direction is definitely more Peter Jackson than actual Tolkien (though it's still very aesthetically pleasing). But the gameplay is impeccable and gives way to a bunch of little silly stories in the midst of the bigger narratives of the game. Shame that we never got any other game that makes use of the nemesis system.
5. Divinity: Original Sin 2.
It's basically single player D&D, which is the expectation with Larian. And that's what makes it one of my favorite games in general. The gameplay is strategic fun and the freedom of builds is nice. The game becomes quite silly once you get familiar with it. The main plot is one of its downsides, what with the Divinity series having the most inconsistent lore you can think of, but most of the companion storylines are quite interesting and fun to explore.
Honorable mention: Dishonored.
I'm not much into stealth games, but I absolutely fell in love with Dishonored when I played it. The morality system, although admittedly rather barebones, gives a nice little bit of uniqueness to each playthrough, not to mention the bunch of different routes you have to complete each mission. The story isn't anything wild but it's still nicely written. And the aesthetics and ambience of the game are aggressively british but in a good way.
