And, to be real, the pace at which Starfleet radically would change its uniform especially in the periods between TNG and DS9 has always been a point of contention amongst Trekkies. Think about it. TNG began in 2364 and DS9 ended in 2375 which is only eleven years. In eleven years the Federation supposedly changes its uniform four different times???
So even though it kind of bothers me that there isn't one single uniform representing the Federation in this game, the show wasn't really logical either. Most species stuck with the uniform that worked for them but the Feds are always trying to be the fashion stars of the galaxy. No wonder the Klingons want to destroy us all
