I notice that the Vulcan Captain provides much of the benefit of the Freighter Captain but without the combat penalties... perhaps the Vulcan Captain's ability should be toned down some? Or is he significantly more expensive than the Freighter Captain?
And when you say +/- to Combat perhaps you should say to Attack? Combat implies both Attack and Defense.
What if a player chooses to put NO captains on his ship? Surely there should be some sort of penalty... (This could be beneficial for Ferengi military ships!) Perhaps give all ship hulls a -50 to attack/defense and all captains a +50 plus their regular bonuses/penalties?
You misspelled "nacelle" in "nacelle engine"...
If you're using QNP you really shouldn't use bonus movement points as they're tacked on directly to the ship's movement after you divide by engines per move...
I *think* "Bussard" is spelled with two s's
If Cloaking Device VI-X is an addon to I-V, shouldn't it have a different name?
Isn't the Sovereign class bigger than the Galaxy class?
The description for the Scout Cube says it's a sphere...
mmm new graphics, and the tech lists in html format!!!

(I like the O2 ice world with the cratered glaciers!)
Can't wait to see this mod in action!

(Of course I'll get everything confused with Atrocities' Star Trek mod!)
