The Morning Star is just a Space Lincoln.
Also, a trebuchet could take on the ship and the catapult at the same time.
That spaceship is nice and all, but can it hurl 90kg heavy stone projectiles over a distance of 300 meters? If not, then it is clearly lacking...
24 hours in, and I knew you wouldn't let me down!
Pretty sure a mace loses to the catapult. Or at the very least it depends on the range the two weapons start at.
