Although true to the hack'n'slash genre, nothing amazing, but fairly entertaining at the best of times.
However, it would still be worth a look for some hardcore hack'n'slash fans. The graphics arn't too shabby, and as mentioned before, the game can take some time to finish (not to mention being a cheaper title for the psp.)
Quests are average though, with not much variation.
Overall not bad, if you see it cheap and love hack'n'slash, go for it, but don't be surprised if you end up getting bored fairly quickly. Some better games have been made since the release of the psp.
