Slightly tangental topic: Ok, I'm gonna brace myself for the inevitable flames here as I say this:
I bought Rebellion off the shelf when it first came out.
And I actually enjoyed playing it.

Ok, then. Yeah, I really did enjoy this game. People complained about the interface, but I never really had a problem with it. Just a week after I bought Rebellion, I read a review in a gaming magazine (maybe it was CGW?) that said that the Rebellion interface was horrible, unwieldy and completely counter-intuitive. My jaw hit the floor when I rad that because I thought the reviewer couldn't have been more wrong.
Rebellion lost its appeal once I kept beating the computer AI on the highest difficulty. Come to think of it, I didn't lose to the computer even once. The micromanagement actually did appeal to me. The graphics were lackluster (especially the space combat stuff), but managing resources and logistics was quite fun.
But my main complaint about Rebellion was that it was too easy. If it had been possible for me to lose to the computer, it would have been much more enjoyable.
I also want to say that I NEVER bothered with Force Commander. Once I saw the reviews that showed pictures of the control interface take up a full THIRD of the screeen (Jesus Christ, Blizzard's Starcraft had a WAY better interface than that and it came out at least a year before Rebellion!), I decided that FC wasn't worth the price of the cardbord box it was in.
X-wing (the original) and Tie Fighter were both great games. But LucasArts then made a HUGE mistake in their subsequent space sim games that both FS games managed to avoid:
When LucasArts made X-Wing vs. Tie Fighter, they made turning your fighter contingient on your velocity, i.e. the faster you're going, the slower you turn.
This one change from the original games RUINED X-Wing vs. Tie Fighter AND X-Wing Alliance. As a result of this change, every time you need to change your direction, you have to slow yourslf down and turn your ship into a sitting duck. By completely changing the flying dynamic, LucasArts made their space sim games unplayable.
LucasArts forgot the first rule of business marketing: If it's not broke, DON'T FIX IT!
It is this mainly reason (but there are others) that I feel that the FS games are products truly above and beyond the caliber of the LucasArts space sims. (I'll debate Origin's Wing Commander games another time.)
As I end this rant, I just want to leave a little something behind for the folks at LucasArts.
*farts in general direction of LucasArts Game Studios*
Thank you for your time.
(Note from Management: The above rant does not preclude me from purchasing Jedi Knight 2: Jedi Outcast (contingient upon favorable reviews, of course), nor will complaints about management of the Star Wars franchise preclude me from watching Episode 2: Attack of the Clones in the theater on May 16. Just FYI
