Wilson. Keep things simple and stop nitpicking.

If I have a ship, it has a top and bottom etc. So if you were to say your ship came out above mine, its obvious that the ship came out relative to the top of mine, thus being above. 

What's so hard to understand.. Why use 3d or 4d coordinates which would require calculus and trigonometry to figure distance speed and angle.. Like what if my ship is coming at a 30' angle from the aft of your ship, hell its coming from your 125' horizontal by 77' degree vertical from your ships center of gravity. With my ship spinning counter clockwise at 2 meters a second at a distance of 1542km at a speed of approximately 700km/h. And at that moment, your vessel is travelling forward relative to your own center.. At a speed of roughly 250km/h.. If you use metric.

I mean seriously Wilson. You want watts calculated for weapon output and half life measurements for any atomic structures? Shit lets do core temperature and armor density at point of scan.. Or maybe drift and spin of your ship.. Ya know, throw some astral winds etc. Oooh and the mass of a nearby moon to calculate the gravitational pull on the ship. Imagine calculating fleet actions. That would be pretty ridiculous! Plotting individual angle of approach and distance so that your ships do not bump in to each other while traveling. 

Should I continue explaining how entirely fun free a rp based on math homework would be? Or can we stick with the generic anime style combat and keep this simple..
