After Ursula's quest you see the ending which would have us to believe that there's a sequel in the works. However, my question is, since Valen's quest is 'advanced' does it continue the story started in Ursula's or is it a retelling of the same story? I need to know whether to try to play through as Valens or not.
I think Valens is just considered advanced because he isn't as strong a character as Ursula so the early going is a bit tougher. There is a Valen quest for a time before he meets Ursula. But once they meet it is the same. I didn't play the Valens one all the way to the end again, but I think there are a few differences. I get bored with a game, no matter how good it is. So rarely for me worth the time to play over. But, if you liked it give it a try.
