Engines are what move and rotate the ship. There are 3 properties that the engines imply in the ship:

• "Acceleration";
• "Maximum speed";
• "Maneuverability".

The bigger the ship, the more engines it will need for it to be able to move. Let's assume that we have 2 ships of different sizes but with the same engines. In this case, the smaller ship will be more agile and faster.

There is a 4th property called "hyperspace" that controls the waiting time between jumps, and the maximum allowed distance.
