Should I get them?
Do have a decent joystick? If so, then I would definitely recommend Freespace 2. I'd personally say that it's probably the best space-sim ever created. One word of warning if you don't have a joystick: I've heard that it's not very intuitive to play without a joystick (though I can't verify because I haven't tried it myself), but it's a great game if you do have one.
