How large of ships can our engine support? Pretty large. One of my favorite things about game development (really just about computers) is seeing simple rules give rise to complex and beautiful phenomena.

For example, making a huge grid of 2000 railguns and then firing them towards the center of the ship makes a really cool dragon starburst pattern. Each turret rotates to track the cursor, but at a limited speed, so the turrets make a cool rippling effect when the mouse is moved.

Futher down the same ship engages a fleet of doomed red-orange ships. Presumably they are to busy trying to dodge do enjoy the nice sweeping pattern of the projectiles.
