Beaten so far:
Luigi's Mansion 3
Jamestown + (could probably put this in the beaten category but there is one extra mission I still didn't do)
TemTem (just got it yesterday)
CrossCode (really cool and extremely well-polished indie game I found on Steam, still in Early Access)
I play a lot of games, so I'm probably missing quite a few. Also, some of these were right around the new year and may have, in fact, happened last year. Also, some of my "currently playing" I may never play again, but I haven't yet consciously determined that I'm done with them. I also tried out a couple of the free EGS games like Farming Simulator 19, Braid, and a couple others which I can recall playing this year but not their names. Briefly checked out Path of Exile to see what new things are in the game since I last played (and since Tencent took over).
Kirby Star Allies: Second time playing through this game with my daughter, but this time we got everything in the main adventure mode.
Jamestown+: Playing a shmup with a 6 year old is more of an encumbrance than anything else, so after trying the final level dozens of times and only coming close once or twice, I decided to just play the level solo just to be done with it. Really enjoyed this one. :)
CodeVein Demo: lol, but I technically did finish the demo for this game. If it wasn't full price, I would think about picking it up, as the demo was a lot of fun.
Death Stranding: I played this a ton during the first couple weeks after release, but then I fell off the wagon and didn't get back to it for a month or so. Recently, however, I've found myself putting quite a lot of time into it, despite barely progressing the main quest at all since the new year.
What I like most about this game are the surprises along the way. Very high quality content, and putting the extra effort in to do side missions pays off well (oftentimes in the form of new items or equipment that you wouldn't have gotten otherwise). Given that I haven't exposed myself to very much information about this game, I have little knowledge of how far I am compared to how much is left (and I don't really want to know either). There are also several mechanics that I'm unsure about as well, but I imagine that at some point I will make sense of it.
TemTem: Made it to the second island.
Control: Haven't really played at all since, but I should really pick this back up again, as I was enjoying it immensely.
Same with CrossCode.
