12 Games with a sci-fi setting like Heart of the Machine that you should try

Real-time strategy genre has always been about domination over your opponent, and Civilization in general expanded on the concept. Civilization 5 allows players to pick one of the 43 civilizations available in, including DLCs and the expansions.

Civ V's systems relocated to an alien planet, with affinity paths that visibly change your units as you commit to one. The alien wildlife adds early pressure Civ never had. It was criticised for feeling like a reskin — the diplomacy is shallow, the victory conditions blur together, and the planet never develops the character Alpha Centauri had.

Turn-based tactics stripped to essentials: unit triangle, terrain bonuses, capture points, and COs whose powers meaningfully change how you play. Readable within one mission. The campaign difficulty spikes sharply in its later maps, and there is no undo — a misread on turn three can cost a map you then replay from the start.

The dual-screen entry: two COs per army with tag powers, plus a much longer campaign than its predecessors. More systems on the board than any other entry. Those systems are also the criticism — tag powers can swing a map decisively, and the balance between COs is looser than in the earlier, tighter games.

The most thematically ambitious 4X ever made: factions built on ideology rather than nationality, terraforming that reshapes the planet, and a unit designer that lets you build exactly what your doctrine implies. The writing is exceptional. The interface is genuinely archaic, and running it on modern hardware usually requires community patches.

X-COM: Terror From the Deep is a strategy game, the second installment in the X-COM series and a sequel to X-COM: UFO Defense that moves action from the outer space into the Earth’s oceans. The story unexpectedly references to Lovecraft’s novels, as you fight aliens that want to reawaken their unstoppable leader who slept under the sea for hundreds of years.

Rusty's Retirement is an idle-farming simulator designed to sit at the bottom of your screen allowing you to work on other tasks while caring for your farm! Grow crops: Plant crops and watch Rusty get to work as he waters, nurtures, and harvests.

###Microsoft’s tower defence The game is one in the genre of tower defense, developed by Hidden Path Entertainment for PC and Xbox 360. Later it was ported to the Mac, and for other consoles in 2013.

Command a team of 5 elite soldiers against an alien horde of 100,000. Surrounded on all sides, you must outmaneuver and outsmart the enemy. The enemy is closing in around you. Your soldiers are being flanked and the perimeter is slowly collapsing under a vicious alien assault.
