I don't mind anime style presentation, but it's a very odd thing to have in a video game. When I finish a chapter, I don't want to see a preview of the next chapter. I'd rather just jump right into playing it, you know? It's not like having to wait a week to see the next episode of a show.
So, would you say the story is better in Illuminus than in the original? If so, I might try to grab it when the price drops a bit too.
