But of course you could have different races with different mass to movement ratios. And you could have different ratios at different ship sizes (for non-Newtonian engine types). And you could have different engine types for different races too, resulting in a very complex but niffty multi-genre universe. And that's just the movement points
Finally you can have different components to change the amount of combat speed the ship has. So a race could have incredibly slow but highly manouverable ships! (ie Early Trek. Just the fighters in SWars)

Man, this will be a very cool mod when it's done! (even if the Newtonian movement isn't used of course)
