One thing that's always fascinated me, though, is Gen. Dodonna's line in the movie, "The shaft is ray-shielded, so you'll have to use proton torpedoes." It would be interesting if a huge ship carried a "ray-shielded" mod that made certain parts of it only vulnerable to ordnance, or perhaps requiring an ordnance hit to "crack the shell".
Wow! Neat idea!
For example:
Ray Shields. Modification. Large ship only.
After you are hit by an attack that is not a [torpedo] or [missile] attack, turn all [crit] results to [hit] results. Then cancel all but 1 [hit] result. If you are hit by a [torpedo] or [missile] attack, discard this card.
