Fighting in Space Is Like Riding a Train. Possibly Naked.
Best description of highly realistic space combat I think I've ever read: "You and your opponent are glued onto the top of trains going in opposite directions. You have laser pointers and can try to blind the other guy from 35 miles away._ If you fail to blind the other guy, you can throw hand grenades at each other as the trains make their closest approach. Those hand grenades are small nuclear weapons…and if you're very quick, you can shoot them down with the laser pointer. You have no real way to change the speed of the train, or to take it off the tracks." It only gets better when you realize that you're wearing nothing except a big, glowing, neon sign that points at your arm and your butt.
