Thanks for the tips on KOTOR, guys.
I was aware of the difference. It's the reason I decided to play the 2 Jedi games first. When I was installing all my games onto my new computer I was reading the Wikipedia entries of each as they installed.
I noticed KOTOR seems to be fundamentally different so I figured I'd jump into the FPS games first, then give it a try.
I also have Republic Commando to try as well. Lot of catchin' up to do!
