The Rose Princess

Okay it's funny. And I'll be totally honest I haven't finished it yet, but I really like it. It's weird, but I really like it. She's a girl who gains four cards and when she kisses them guys with special abilities come out and save her from her predicaments, but it's so much deeper then that, and it can be so much more serious. I think most of us girls would really like it.

Final Fantasy XII

This is the story of a world called Icalice. It is a time when the existence of magic is still commonplace, and oaring airships cover the sky. Princess Ashe has vowed to restore her ruined country. Together with a few companions, she waits for an opportunity to strike back. A direct adaption of the RPG.

I really like this one, probably because I've been on a FF binge today.
