Reading all the spoilers, I didn't feel spoiled at all lol. There were various instances through out the game that Goddess was a clear bitch and has joined hands with Richard and others. Alicia also had some very good personality points, she was more leader like than Aura in Part 1 when Aura was supposed to be the Hero. And her fixation with Aura also meant that they were involved at a much deeper level.
Still, will love to see a Sequel where Aura goes on to invade Earth only to see Alicia becoming hero again and their role reversed with Alicia trying to bring back Aura to her side.
