Loved X-wing and Tie Fighter, and X-wing Vs Tie never got to play but I figure I would love it too. I did used to play Tachyon: The Fringe. If you're looking for good fighter action, you might try the Evochron series. Also, Elite: Dangerous comes out next year, and CCP the makers of Eve Online are working on EVE Valkarie, which is their space superiority fighter sim.

BSG's setting, as far as space physics, and combat in space and all was done really well, I think. There are things you can do in a Viper that an X-wing never seemed designed to do, even though they have similar aesthetics, and fuselages and stuff. The way they made use of RCS thrust vectors was cool. I might have to watch it again, now that we've been talking about it.
