The second disc was alright. It wasn't as good as the first one, but I didn't dislike it.

Basically almost every area of the world had already been explored by the start of the second disc, so I guess we weren't missing out on too much exploration.

I'm never ever annoyed by storyline progression, so the whole Fei-in-chair bit didn't bother me in the least. I really don't care if my game is linear, as long as I get a good story I'm fine. As oppose to that I cannot stand non-linear plots.
