It's not Star Wars —- they are all their own games —- but you can check out Star Wraith's Games. There's also Starshatter, another indie game, and — well, these are more Elite / trading style, but there's the X series (X3: The Terran Conflict, etc).

If you never played Freespace 2, GOG.COM has it (very much inspired by the Wing Commander and X-Wing / Tie Fighter series), as well as a few other space combat sims that might scratch the itch.
