Spaceflight simulator games are a popular category with many different gameplay styles. These types of video games allow users or gamers (players) to simulate various scenarios in the real world by designing spacecrafts for space missions. Players usually start off as astronauts who have just landed on Earth and need help launching their rockets into outer spaces, while they also face challenges such as navigating through a complex networked universe.

The game offers players an opportunity not only of building themselves but to design new systems that can be used in the future by other space missions. The most popular games are those with open-ended scenarios where users have more freedom and creativity than traditional simulation tools, allowing them greater control over their characters' actions while still providing a realistic experience.
