Well, let's see... This is what I found doing a little research:
Mark Hamill (ex-"Luke Skywalker"), who voiced Ripburger, has been in a lot of cartoons; as a matter of fact, he was the voice of The Joker in "Batman: The Animated Series". On the other hand, he hasn't been in many games since FT. Some of them were "Forgotten Realms: Icewind Dale" and "Soldier of Fortune II: Double Helix", but (ironically) none of them are Star Wars-related.
Roy Conrad (voice of Ben) participated in "Rebel Assault II" and "X-Wing vs. Tie Fighter".
Kath Soucie (voice of Maureen) took part in "Fallout", "Outlaws", "Star Wars: Galactic Battlegrounds", and "Kingdom Hearts" I and II, among others.
