Star Wars has a long and rich game legacy. Long before SWTOR was a gleam in a developer's eye, many other games came before with varying degrees of success. In the mid 1990s, LucasArts released a number of popular space combat sims. The most highly regarded of these was Tie Fighter, and many gamers consider this game one of the best space combat sims of all time. Swtorhub.com takes a fond look back at Tie Fighter.
One aspect of Tie Fighter that sets it apart from X-Wing is the sense of advancement. In X-Wing, you flew different fighters based upon the mission. In Tie Fighter, you have to work your way up the food chain to be able to fly better fighters. You start off with the lowly Tie Fighter, which is fast but has no shields. Run into something or get a few hits and your fighter explodes into so much cosmic debris. There was a real sense of achievement when you finally got to fly the Tie Interceptor or Tie Advanced (glorious shields!).
