Can someone remind me why an earth video game is a better flight simulator than anything the sci-fi military has access to? Or is it just his ship being OP
His ship is OP, and he's practiced things that normal people wouldn't, like charging headfirst into a swarm of crystalline life forms that can destroy your ship with a single touch.
The advantage isn't that an Earth video game is a better simulator, it is that he honed his skills in a game with minimal penalty for death and no expectation anyone will be doing this IRL. And now his pro gamer instincts deny conventional tactics because he has a LOT of practice doing things the crazy way.
