I enjoyed Jedi Outcast but I fluked the ending which was a letdown.
For me nothing feels more like being inside the Star Wars universe than :
The radio version had Luke having a crash course on X-wing controls on a simulator and that what it felt like when I was a kid.
Vector graphics (like BBC Radiophonic music) still feel futuristic to me (I know Star Wars is set in the past but I digress).
The opening mission of Rebel Assault is love letter to the game.
