Mostly Surviving Mars and Doorkickers at the moment.
Doorkickers is good. Do you remember a game from childhood called Endless War? Piece of shit where it was all a top-down view, campaigns for SWAT, Korea, Vietnam, WW2, etc, and the AI would just sit there and react to you. It was good for being a kid playing a game on the Internet. Doorkickers is like that but as an actual polished game. You are SWAT, top-down view (but surprisingly detailed graphics for that, it's not pixelshit). Quick time to kill. You direct your troops in real-time with pause laying out plans of attack, can beat entire maps with a single plan set up at the start. Like Rainbow Six: Siege, you smash doors with breaching charges and hammers, use sniper support, flashbang enemies, etc.
It's often brutally hard, everything can be beaten but a lot of it I think is random luck based and unfair. Bullshit where you have to cross through 10 heavily guarded rooms and the moment a gun goes off (immediately) they shoot the hostage.
Surviving Mars is a time sink. Tropico (same people) but with more detailed infrastructure and no politics. You plan a mission, starting with a sponsor (a nation-state, a company, a diplomatic mission, etc.), a site (map), your initial payload. You begin with just drones, and have to establish enough of an operation to even be able to receive your colonists. You have finite rockets (with the ability to acquire more) and you have to refuel them, with fuel manufactured for water, for the return trip. You have to export rare metals to make profits to buy the imports from Earth. You have to make power grids for everything (including keeping the workers from freezing to death), air and water pipe grids, and feed them, which natural disasters will randomly break, forcing you to think like an engineer with redundancies built in, cut-offs in the grids to isolate leaks, storage units, and storage units where you need them (no good having storage if they're all on the wrong side of the shut-off). I like all of that, except it's a truly awful design choice to have the power lines and connections between domes not be able to cross each other.
Then you also have to entertain them, potentially even found a space tourism sector. I don't think they can revolt proper but I've already seen them (because of repeated incidents of freezing from power blackouts and food shortages) destroy very valuable equipment. Like a lot of these city-builders, I find that the game rewards managing the colony benevolently too well, you are better off (as it usually is) just fulfilling all wants and desires instead of being able to use repression.
It's compelling stuff. Micromanagement hell. All the basic transportation, construction, and other jobs are carried out automatically by drones, and you can build static stations or buy mobile units for that, and you can set up regular supply lines or special orders with transport rovers. The problem is, if there's a way to say things like "keep the stock of this good within this range" or "go as far as you have to to get materials to do maintenance repairs," I haven't seen it. At the point that I'm at now everything is breaking all the time, I keep running out of food in one or the other side of my chain of domes, and I've burned through all my decent applicants (it's too big a pain in the ass to worry over, but if you want to autistically pick out the candidates with the right stuff, you can).
You've got, like Tropico, citizens with personality traits, but it's usually dumb shit like "epic gamer gets +10 happy points when games teehee" and there's too many of them to keep track of them, other than perhaps to pick out specific ones to follow for a story (like my first Martian-born citizen, or a religious leader in my first batch of colonists that converted half of them).
I kind of wish there was some light warfare in it or rival colonies (they made a DLC but everyone says it basically adds nothing of value). As is I do get a mixture of feeling like I'm founding Jamestown while also engineering, which is a good feeling. Overall, really good game so far.
