TIE Fighter was possibly one of the greatest flight sims of all time. I love the fact that you stay loyal to the Empire for the whole game - instead of the stereotypical "the Empire's evil" realization scene that forces you to defect.
Meanwhile, I point out that X-Wing had the original movie targeting computer, or a facsimile of it, as demo'd by the pics I posted earlier. The targeting computer used to hit the exhaust port (with the yellow grid walls and the timer) is, on the other hand, that little screen that comes down in front of them.
But I'd definitely like the accurate TIE computer. I've always disliked cockpits that are just pretty animation with no real use.
