According to ESRB, this game contains: Alcohol Reference, Fantasy Violence, Mild Language, Suggestive Themes
Parents: don't let that long list scare you. I don't recall the “alcohol reference” off hand and, although players do break off enemies' body parts, the violence isn't bloody at all. Also, Valkyrie Profile 2 focuses more on its heroines' fighting skills than their bust size, which is more than I can say for most Teen-rated role-playing games out there.
Casual gamers should probably stay away. The battle system takes a little while to get used to, but more than that, Valkyrie Profile 2 is designed for the kind of person who likes to spend 60+ hours poking through every nook and cranny of a single game.
Anyone who fits the above description will have a lot of fun with Valkyrie Profile 2. After playing for over 100 hours, I still haven't found everything.
Girls and women will have a plethora of female characters to play as, and they all kick butt pretty hard. (Most are einherjar, warriors who died in battle that valkyrie bring to Valhalla as soldiers for the god Odin's army).
People who haven't played the first Valkyrie Profile (in either PlayStation or PSP form) shouldn't have too many problems playing this game. I played this game without any previous Valkyrie Profile experience, and understood the story just fine. (Since Valkyrie Profile 2 is a prequel, you don't need backstory from the original to figure it out).
Deaf and Hard of Hearing gamers should have no problem with the gameplay, but the cut-scenes are a little hard to understand without sound. All speech is captioned, but there's no visual cue for who is speaking. You can't even look for whose mouth is moving, since the lip-synching in this game doesn't always kick in right away.
