Yeah, but that ending doesn't count. See, in a fighting game, there are so many endings that they can't all possibly count. Hell, most of them can't happen. For that to work, everybody would have to fight Cervantes and SoulEdge, and everyone would have to get or destroy the same sword. The reason everyone thought it Li Long was killed by Cervantes, is the prologue artwork to Soul Calibur 1. It shows Cervantes standing over a beaten Li Long, and the words "Those who managed to reach the cursed sword cursed their fate as the sword devoured their souls" or something to that effect.
