To be fair, the realistic space combat video game genre really doesn't exist, that I've seen.

You can get pretty hard-realistic combat aircraft sims. Not many, but they exist.

But in space combat games, you're always playing something roughly like Star Wars. Which is cool and all, but just not what actual space combat would likely look like.
