NCC=New Construction Contract
NX= New Experimental
NCC doesn't stand for anything. It was devised by Matt Jefferies, art director of the first Star Trek series. Jefferies, who is a pilot, based NCC on 20th century aircraft registration codes. In such 20th century usage, an "N" first letter refers to an aircraft registered in the USA. A "C" second letter refers to a civil aircraft. Jefferies added a second "C", just because he thought it looked better. Think of it as being like the arbitrary three-letter code that's part of automobile license plate numbers in many states.
Hey at least you got yours I got the Digital Deluxe Edition from D2D and I got some of the things but not the NX or the "KHAAN!!" emote, I really wanted that Khaan emote LOL, or the Bloodwine toast. Now who would I contact? D2D or Cryptic??? Anyone else having this problem?
