I just spent some time looking at the core designs and I see that the weapons and shields are nearly all incorrect. Beam ships are arrayed with Mass Drivers and/or missles and vice versa. Ships with Armor actually are arrayed with shields, ships with no defense have shields and armor.
Actually, they look good and this is of little importance as long as the ships perform as if the weapons/defense rating is correct.
I presume that regardless of what I see on the ship it is coded to match the description.
I thought it was sort of funny and I wondered if there was a pool at Stardock betting on how long it would take some wiseguy to point out the errors.
