It's my turn, let's see if I don't take too long, if not I'll edit it later and add more!! My favorite gaming library is Steam, however I already have so many games on Epic... but honestly I haven't even touched it jajaja life doesn't give me time.
Taking advantage of the fact that statistics of sessions, games, etc. can be obtained, here is the Steam summary of 2023:

Stalker CS: I enjoyed it quite a bit, but because of the great idea of adding mods to improve its gameplay, I encountered various bugs. Until I reached a point where I couldn't continue the game, so I had to reinstall it and look for a save in the area where I more or less left off. A bittersweet feeling, but hey, it had been so many years that I had been pending to resume the saga that it was worth it.
Doom 64: I had never played the first Doom, one of the most classic and iconic in its genre. Thanks to this one I was finally able to have the experience and enjoy the quintessential kill-fest. Of course I still have to play the original Doom, but I enjoyed it 
The curious thing is that I started playing it on Epic Games, but since I also had it on Steam, I preferred the latter platform.
GTA V: I finished the story mode last year, but I played a few games and a while in online mode. As always, “great game”.
Quantum Break: I gifted it to myself for my birthday last year. I liked it, it's noticeable that Remedy is behind it (Alan Wake, Max Payne). But… it was a bit confusing for me because of the time-related plot (even though I love time travel stuff), very cinematic, some save points were very poorly planned. But well, overall I think it's a good game.
Portal With RTX: Simply the first Portal but getting the most out of ray tracing. It's always a pleasure to play Portal 
Portal Reloaded: With the bug for Portal 1, I got into playing this mod based on Portal 2. It's very good, but I left it halfway because the difficulty level seemed too hard to me. However, maybe someday I'll get motivated to finish it.
Tomb Raider IV: The latest revelation. Well, it had been about 15 years since I played it “for the second time”. I was eager, I spent a very entertaining Holy Week and enjoyed a classic xD
Farming Simulator 2013: I have a superior version on Epic, I'm not sure if it's the 2017 or 2019. However, I was eager to play it for a few hours since in 2013 I barely played 8 hours. I ended up playing almost 100 hours jajaja
It has some shortcomings that I hope will be addressed in the new versions. I imagine that a lot of time has passed.
Serious Sam 4: I barely played a few hours, let's see if I finish it this year. It's a game that's good for thinking little and de-stressing xD Well, sometimes you get stuck and have to use your brain a bit, but the best thing (sometimes overwhelming) is the intensity of the combat.
Stalker Lost Alpha: I had more fun with it than with Clear Sky, but I got a bit saturated and left it parked. Let's see if I continue this year and finish it. There's already a thread on the forum about the game, if you like the saga it's highly recommended.
Red Dead Redemption 2: I've played a little, the tutorial and a bit more. It's a great game, let's see if I get fully into it. Many hours appear in my profile due to the tests I ran to test the PC.
GTA III Remaster: I bought it on Christmas, well, I got the complete pack. Honestly, I see it as a rip-off that I have to pay €9.99 for a game that I already have and whose improvements are very poor. I understand that someone “new” might want to sell it to you as is and at that price I think it's perfect, but for those who already have it, it's a bit of a nonsense.
I knew it already, if I bought it is because I'm a huge fan and yet I waited a year to see if they improved something, but apparently they didn't do much more, at least in GTA III.
I've played a few hours, maybe I'll get excited and finish it, but it's not my intention. I'll tell you how Vice City and San Andreas are, these are the ones I'd really like to play again completely.

As for other games outside of Steam, the summary would be this:
Minecraft: Little just to try the RTX mod. It's amazing the effects of light and water.
Word of Warships: The only multiplayer game I play. I'll have to leave it a bit more aside if I want to advance in my list of games this year xD
Tomb Raider-Custom Levels: Of course, my strongest addiction can't be missing.
I'll detail the levels I've played later in case it helps someone, or if someone gets motivated to give it a little more effort
