According to ESRB, this game contains: Language, Violence
Parents might want to be cautious with this game. Some of the characters are dressed in fairly provocative outfits, though there is no explicit sexual matter. There is also some questionable language and scenarios that might not be suitable for younger ears. It's not really R-rated material, but it's definitely stuff that you don't find in the average video game.
Fans of Eastern-themed games might want to check it out, just be aware that the story is nowhere near Final Fantasy quality. There is something appealing about to a young swordsman traveling through a scenic world, but nothing ever gets filled in to any real level of satisfaction. The RPG elements are weak, and the action isn't strong enough to carry it. It's not the worst PSP game I've played, but it could be a lot better.
Action gamers interested in the combat will most likely be disappointed. It's a lot of good ideas that fail to come together, and the end result is something that feels very slipshod and haphazard, not to mention that with the large numbers of enemies attacking at the same time, it can be almost impossible to play without heavy use of the overpowered magic system.
Deaf and Hard of Hearing gamers will have no problems. All of the spoken dialogue is accompanied by visual text, and any important information is usually extremely noticeable through visual cues; i.e.- when combat starts, the hero pauses and visibly draws his sword. I didn't encounter any accessibility barriers at all. Thumbs up.
