Interlude and After Years are both bad and do not add value, IMO. But I won't take marks off for their inclusion. I like the PSP version for changing out party members and that's it. I don't even particularly care for/about the lunar trials. Just like to be able to put Yang in my party. I don't remember the translation being particularly bad. Is it different from the GBA version? I actually kind of assumed it was pretty much just a port of the GBA with Interlude and After Years added.
