Science fiction has been a popular genre for AAA games for ages. From early text adventures like Space Quest to the likes of Mass Effect, Dead Space, and Halo, there is no shortage of sci-fi games from big companies. Even some big franchises normally considered outside the genre have dabbled in it. Call of Duty, originally a WWII shooter, experimented with science fiction aspects in Ghosts, Advanced Warfare, and Infinite Warfare. But while many of the most iconic titles might be properties of big companies like EA, Ubisoft, or Activision, they do not have exclusive rights to the genre. Smaller independent games have also enjoyed exploring imaginative technology or strange new worlds. Sometimes, these end up exploding with popularity and gaining a huge following.
