I still haven't figured out why lol. When I used to play Jedi Knight Outcast, and later Academy, I was in a clan full of other SW fans. Unfortunately they were scattered across the world, but the majority of them all had a lightsaber like that. Fun, fun times and fond memories.
I love Star Wars, but we don't have those kind of sabers here, just those plastic ones that make swoosh noises when you swing them. >>
That, and I lack friends with good enough taste to like Star Wars lol.
