But then if K-7 was sized correctly (should be about the same size as Connie) the non-trekkers would cry foul when they saw it since most people expect their starbases to be bigger than the ships they fly.
I think this statement bears repetition. As much as part of me would like to see everything sized properly, I'm also willing to admit that it would probably look strange or "wrong" if they did. The starbases in the game would be about the size of those little asteroid mining bases in-game. They wouldn't be visible from a distance, and in situations where 20 or so players are parked outside, would be lost completely in the crowd.
It bugs me most with DS9, as that's "my" Trek, but I think the recent resizing done for the Featured Episodes was a reasonable compromise.
