I'm personally partial to Knights of the Old Republic. It was one of the first video games I had owned since I was very young, my very first RPG, and it re-introduced me to a franchise I had only really been peripherally interested in at the time. And then KotOR II came out, and proved that Star Wars could be about more than black and white, good vs. evil - made it feel much more real
. I lament that TOR robbed us of a proper continuation of that legacy.
However, I do have very fond memories of Pod Racer, as well as the Phantom Menace game - I remember the Naboo levels in particular as some of the most difficult and stressful times of my youth.
