A minitures game like that would have to rely heavily on record keeping due to the inflexability of the physical representations. Just thinking of what you would have to do to keep track of what is where and how its facing etc would leave me wondering whats the point of even having minitures in the first place? Your already just writing down where the ships are in elevation relative to the game surface, along with pitch, roll and yaw so why not just keep track of the ships location along the game surface? This could be pretty intersting for small scale (1 or 2 ships/ player) but would really bring down the enjoyability of a fleet based game such as this.
I can do you one better.
Relativistic Velocity.
Now that you have to record where and how each ship is pitched, you must now include the fact that they are all moving and the distances involved. Now every projectile weapon must use counters like when firing torpedoes, so a firing ship has to fire at where their target will be at a later turn, not the current one.
Oh, yeah. Also take into account the fact that if a ship if far enough away, you are seeing an afterimage. The light from it has taken so long to cross space to your sensors that it may have had seconds, minutes, or even hours to move away from it's current position, and you are just now seeing it start that move.
Plus, if you fire at it., you have to aim at "where it will be", and then hit the button. It will take a certain time to get to the targetted spot, and then that same amount of time
again for you to see the light reflected from where it was supposed to hit to see if you even scored a hit. oh, and that's just for lances, because they are travelling at the speed of light. Projectiles will be magnitudes longer than that do to their slower velocities.
....Nope. "2D naval game in space" sounds and plays like more fun and much less of a physics midterm.
