On an entirely flipped side of the coin, I bought SFC3 because it *wasn't* SFB. And I can think of a fair number of others who did. Of course, all I continue to play it for is TNZ, which is just a thoroughly awesome mod an community. If not for that... well. But to me, SFB has never felt like a real trek game. Things... just don't feel right. SFC3 isn't quite entirely there, either, but it's close enough to count, especially with the DW and TNZ mods to plug some gaps.
My only comment in response to your comments, Nanner, at least at the moment, is that I have some issues with power management (hotkey slider memory sets would be killer), but Let's not confuse fine detail control with quality. Can you *really* juggle that many sliders in the thick of combat? How far can you split your attention? When does micro-managing your ship take over from playing the game? the way i see it, what SFC3 has in that regard is right where it should be-- enough detail that you can juggle the power to your liking on the fly, but also little enough that you don't spend most of your time doing it, which means that gameplay doesn't bog down.
Now, if only it was just a *little* more mod-able and we could get a real patch out of it.
