YES! It's crazy, but the music really goes a long way to helping it. The game channels a lot of emotion through it and it equally cements the thrill of the action sequences and boss fights.
I'm 20 hours in at the start of Chapter 10. It's enjoyable. I still want SE to make games better than this, but in the future I suspect we'll look back on XIII a bit like we do VIII.
I really liked XIII and the OST is probably one of my favourite game OSTs of all time.
That said, I think the game failed to really live up to the OST sometimes. I was really disappointed when dust to dust played but
Vanille and Fang didn't really react shocked or sad that their home was completely destroyed. The song was just screaming dramatic cutscene imminent imo. So that left me a little bit disappointed
I did not like XIII-2 that much, but the music is pretty good too. Really like the unorthodox music compared to mainline FF's
I am playing through Lightning Returns right now and I am having a lot of fun. Would recommend picking it up for a decent discount if you can deal with XIII-2-esque cheesiness.
