From the review, "Vanillaware and Odin Sphere fans won't want to miss Princess Crown, purely for the nostalgia value. The port of the Sega Saturn title has some issues but, overall, is a delightful game. After only a few minutes of playing you can see how Princess Crown influenced Odin Sphere and, if you've played Odin Sphere, you'll have no problem navigating Princess Crown.
While Princess Crown is a completely 2D, sprite-based game, it is one of the most beautiful PSP titles. The graphics are very detailed and striking, and the characters are memorable. If you can look past the stark frames, you'll see a stylish game..."
