Well, the original Dungeon Siege let you customize your characters look and choose gender, yes. I still wouldn't call that a proper character creation though. You couldn't choose skills, background or anything else meaningful. The whole point of the character progression was, that you just slowly got better with the equipment you picked up and used in the game. There was no manual levelling at all. Also, no matter what character you created, it had exactly zero impact on the game. In DS3, all the characters have different equimpent and you can play them all as you see fit by making different decisions during the story (again, DS1 didn't let you choose anything in the story, the only decision you got to make was weather to tackle an occasional sidequest or not).
