We all loved Wing Commander, but when Lucasarts released X-Wing we instantly found out how a truly great space-fighting sim should feel. Then Star Wars: Tie Fighter was unleashed and everything else since and before paled into comparison, for this was the absolutely best flight-sim ever. It was tactical, fast, deep, exciting, looked brilliant, felt epic and even sported an excellent plot. Ah, yes, a true gem indeed and one of the most important PC classics.
Mind you, you can (and most probably should) grab the complete, boxed Star Wars: Tie Fighter over at magisterrex. The game includes the original game box, all five 3.5" game disks, the Starfighter Pilot Manual, the reference card, and the troubleshooting guide.
