Summary
Sci-fiis a rich, mineable source of inspiration for game developers, leaving them free to use their imagination to dream up worlds and games that have no need of being realistic in any way. The very first computer game ever,Spacewar!, wasa sci-fi game, making this the oldest game genre of all.
Many modern sci-fi games can feature anopen world mapfor exploration, survival mechanics, complex crafting systems, and meaningfulbase-building systems. They can be single-player experiences, or they can be ideal experiences to enjoy with friends through cooperative gameplay. There are options for players who prefer a purely PvE experience, competitive PvP, or a mixture of the two.

The Frontis a sci-fi game with a twist. Rather than being set in a traditional sci-fi-themed environment, it takes place on a map that looks very much like the real world. However, due to rifts in spacetime, the player and their allies are set to repeat the same battles across time and space. Additionally, creatures from beyond the spacial rift can be summoned and fought.
Base building inThe Fronthas two main purposes. Firstly, as a location to place crafting stations and store materials and loot. Secondly, and more importantly, as a defense against other players.PvP is a huge part of this game, and it can be very competitive indeed. Without a well-defended base, complete with armed turrets and NPCs to protect it, even the largest group of players will be vulnerable.

InAstroneer, players are free toexplore the galaxy, land on planets, and shape these planets to their will. It is touted as a sci-fi adventure game and leans less on the standard survival game tropes found in similar games.
Set in the 25th century, Astroneers are pushing out into the frontiers of space, and base building is a large part of this exploration. Building bases gives the player a place to store items and materials and prepare for further travels into the galaxy. Overall, although the base building is quite simple in this game, it offers a very rewarding experience.

InStationeers, the player takes on the task of building and operating a fully functional space station. This includes setting up power generation systems, as well as installing and maintaining machinery and life support systems.
What makesStationeersmuch more fun is to play with a group of friends in co-op mode. This way, the entire team can work towards joint goals and turn a derelict space station into a successful, fully operational base of operations. This is a fantastic little space survival game that features interesting, goal-focused base building.
