I haven't seen a thread on this yet, so let's do this! I always recommend RimWorld for base building/management, as well as Hades for a magnificent hack and slash roguelike. I also highly recommend Noita -- a roguelike where every pixel is made of some kind of simulated substance -- dirt, lava, acid -- and you find and edit magic wands as your primary way of attacking and affecting the world. I also picked up the Phoenix Wright trilogy during the fall sale. I've been enjoying it, but sometimes it can definitely be too finicky in an old-school way, like wandering around aimlessly until you show a witness a random trading card or something. Decently fun, though, for sure. I'm not mad at paying $17 for 3 of the games.
What about you? What are you playing? What do you recommend?
CHR$(143) -- Very few people know about this obscure indie pile by a true eccentric nerd so I'm going to bring it up first. It's $3!! Just a fucking weird genre-bending mess of Boulder Dash, Incredible Machine, ZZT or Kroz, it's hard to describe but it's brilliant.
Midnight Protocol -- Every hacker media cliche comes together. If you liked the hacking minigames in 2011 and 2016 Deus Ex and would like a fleshed out campaign like that, this is for you.
Phantom Doctrine - xcom-like that's more of a stealth game until you get caught. Actually pretty easy to cheese but it's a fun romp with interesting refs to cold war history. Don't play it just like you would xcom or you're going to be frustrated
Every Zachtronics game.
Seconding Zachtronics games, particularly Spacechem.
