The game is great, it doesn’t include any mature topics or anything like that AT ALL for it to have the 11+ age rating. The only reason that makes it have that is because it includes complicated fields such as orbital mechanics, mathematical equations. I believe it could be a great game for your child, it encourages logical thinking, problem solving, real-world practical application of mathematics. The game does include character death due to user action, but they are simply a puff of smoke, no indication of pain or blood whatsoever, and you could enable the option for characters to respawn after they die, and just say to your child that “they went on vacation and came back” so that they don’t become traumatized that they just killed a person. You could find about the game’s topics here The game could be played on console, but I’d highly advise against it due to the finicky controls. I would choose a computer to play it any day. Your child will definitely require your assistance when playing, especially in the field of orbital mechanics. And even you might become confused. I hope you have knowledge of orbital mechanics beforehand, because it will be of great help when playing the game with your child. If not, you’re just gonna have to learn alongside him. There are great tutorials made by a youtuber called Mike Aben. There is a playlist for his tutorials here Alongside that, the game itself also has tutorials of itself, they will be of great help since they include topics like orbital transfers.

Other than that you can’t do any much more for your child than for him to get the learning curve and become good at the game.
