Finished Valkyrie Profile today. I had a real hard time learning the game (especially the battle system) but once I did I enjoyed it a lot.
Appreciated the unique (and very sad) story, the beautiful background art and character design and sprite animations, the great music (though some of it does wear on me after a few hours), and the rewarding battle system built on button combos (almost like a fighting game).
There were a couple things I disliked about the game. Things I wish I knew beforehand. First is that it's on a time limit. It's possible to mess up your pace by re-entering dungeons to grind XP. Second is that there are some impossibly well-hidden items in the game. Things that you'd need a hundred hours or a knowledgeable friend or a FAQ to find. I know that isn't unusual in RPGs but for some reason I wasn't expecting it this time. (I started checking a guide when stuck at around 10 hours in).
Anyway. Valkyrie Profile was fun & I'm glad I played it. I think I'd enjoy a second playthrough more and so someday I may do that.
