You don't get it. A game which uses Newtonian physics, such as I-WAR 2, is a "realistic simulation" game, whereas a game which doesn't give two shits about physics, but is still a "flight simulator", such as for example any Star Wars game, is a "non-realistic space sim." In both cases you still fly a spaceship, which is what's being simulated.
In EVE you don't fly jack shit. You click on a target and away your unit goes. As far it's mechanics go, it's a single unit RTS. Not a space simulator. The only thing EVE simulates is clicking on shit on the screen.
