Btw, in case anyone is wondering, this character is named "Kirito" from the anime "Sword Art Online II". The character is actually a boy, with an avatar that looks like a girl (sort of like how Peter Pan is sometimes played by a woman in stage plays)...
And yes, that is a Star Wars lightsaber in his possession, though it's properly referred to as a "photon sword" in the anime, and not some metallic sword made to glow... Of course a lawsuit by LucasArts would probably have no basis b/c this photon sword exists within an online virtual reality world only...
