I can assure you it's Engrish. I swear I can hear her say "You never see it coming...", but that's about it.
P3 had a nice soundtrack. The good thing about that one was that whatever English they did use, they had small phrases, like that "I never felt like", and then the Japanese dude writing the lyrics would run out of all the words he knows in that language so he'd end it with a "ta na na na na!"
Yeah, the down time song is stuck in my head. It's actually pretty chill. The soundtrack overall though, it's good. The artwork, though. This is how you make an amazing looking game. Just every little graphic element is so slick, for lack of a better word.
The grinding seems tougher in this one. I don't know what level the new characters get unlocked on, but I think the XP is shared between the party. So I guess it would make sense to add one weak party member to your group and fight the higher level enemies so they get more XP? I'm sure it's not that simple.
I think I beat the first dungeon with 2 members at LVL 11 and two at LVL 10.
