Well, I'll go through my Steam purchase history, because I'm sure I'll miss things otherwise. I still risk missing things I bought elsewhere...
In roughly the order they were purchased (starting very late last year):
I'm one of those folks who doesn't really care for the Metroid series much, and Metroid is very clearly what this game was evoking. It wasn't a bad game, but I didn't overly care for it.
I still haven't actually played Doom, since it ran like garbage when I first got it and I haven't tried playing it since. Not sure why I included it, really.
Stardew had me bad for a while there, and I can't say I'm worse off for the experience. There's something about games with an influential day-night cycle, I've noticed, that makes them tend to be time sinks. Anyway. Stardew Valley is a nice game, in both senses of the word. This'll help sap some of the world-weariness out of you. Also, Abigail.
Nom Nom Galaxy
I wasn't certain I wanted this when I got it, and immediately I decided I didn't like the feel of it at all. Thanks, Steam refunds! It seems like it could be enjoyed by some, but I am not that some.
Frankly, I barely remember this game by now, but I seem to remember it being a fun little minimalistic puzzle game (which seems to be its own genre these days).
The Flame in the Flood
This was actually one of a number of games that my parter bought for herself, but I ended up playing it. It's... not that great. Its premise is somewhat interesting, and the gameplay isn't too bad, but I feel like as a whole experience, it kinda drags. I also severely dislike their character styling.
Hollow Knight is a good game. My compatriot up there is right to have enjoyed it. On the whole, it is a solid game of exploration and combat. Once you get the combat down, it feels great too. I do have an issue or two with it, though. Firstly, there's very little guidance. I get that that is not unusual for a metroidvania (I hate that term), but I have never gotten stuck in one like I did in Hollow Knight. I was scouring the entire map I had seen up to that point for literal hours trying to figure out where to go, and that left a very sour taste. Secondly, even after 100%-ing that game and seeing all that there was to see... I still have no fucking idea what that game is about.
I mean, what is there to say? There's nothing around the edges of this game, no nuance, no mystery. It's just a really fun game to play. I've dipped my toes in games like Day Z and such in the past, but those are... well, they're terrible games, and they clothe themselves in their own obscurity and arcane-ness. PUBG takes them, strips out everything that isn't fun about them, and leaves a core experience that is all you ever actually wanted from them anyway. There's some bugs, but depending on who you listen to, they can get severely overblown. On the whole, the experience is fine, and no doubt only going to get better.
This is a fantastic little game. It's playable solo, but it shines when you get the local multiplayer going. It starts you off by introducing you to some basic tasks, then as you get into the swing of it, the levels start to throw wrenches into otherwise straightforward scenarios. Good for chaos and for mastery thereof!
Lagoon is good fun, like Stadium before it. A stripped down racing game where it's basically you versus yourself, making runs at a (probably crazy) course over and over, carving seconds off of your time and feeling good each time you do. I don't really know what's so appealing about Trackmania, but it's a damn good game.
This is a strange one. The game is all about getting good at its controls, and it feels really good when you do. It just doesn't change up enough throughout the levels though. I didn't finish it, and I can't say I particularly want to. It was fun while it lasted, though.
Kinda like Stardew Valley, this is a nice little game to hang out in and do stuff in. On the whole, pretty fun, but it lacks... je ne sais quoi. Still a number of updates to come though, I believe! (One was yesterday, in fact.)
Not a bad game. I don't know if it has much staying power, but I enjoyed this until I finished it.
Quake is, uh... not that great. I've played Quake II and III previously, but had never gotten more than a level into Quake I. So naturally I put it on the highest difficulty and finished it. Boy, I'm glad video games moved on. (At least, for a couple of years there. Maybe they should have stopper while they were ahead.)
Rock of Ages II: Bigger and Boulder
What a weird thing. This is sort of half tower defence, half 3D platformer, half Monty Python. I... I dunno.
Bought, have not played. I'm looking forward to its release, but I won't be touching it until then.
Monster Hunter Stories
I doubt I could convince anyone about this either way, but heck, I enjoyed this. The oversimplified way of describing this would be "Monster Hunter plus PokÃ©mon", but truth is that it's neither of those things. This just takes Monster Hunter and makes its whole own thing with it.
Cook, Serve, Delicious! 2!!
This is a fun little game. I use the keyboard, and it's damn near a typing game. A good short-time game.
Fun! This is a great little top-down stealth (or not) game. You can find a broad range of tools, and a broad range of obstacles that necessitate them. There's endless ways around situations, and ndless ways that they can go hilariously bad. Emergent gameplay at its finest.
This is dumb. But at least it's fun.
I'd been eyeing this game for a while trying to decide if it would be my thing. Turns out it's not a bad game. I wasn't anywhere near finishing it, but I had my fill after a while. Doesn't seem like the kind of game you'd want to get too drawn into.
XCOM: Enemy Unknown
I'm saving this game for a stream idea I intend to start later, and you'll all be a part of it! (If you want.)
FTL: Faster Than Light
I can see why this game was such a force for a while there. It's great fun!
Getting Over It with Bennett Foddy
I like a challenge and I don't get mad at games, generally, so I thought this might be fun. And it is! But I wouldn't recommend it to anyone.
I also played Terraria (still fantastic), Monster Hunter 3 Ultimate (still good, but really feel the abscence of the quality of life improvements in the newer games), and maybe a little bit of Half-Life.
