I just completed this game yesterday and the whole thing was brilliant. Its decent in length with flawless, classic dungeon crawl gameplay. It's a must have for the psp. The spells system is completely brilliant (i played mercenary class) and simple so you're not thinking what button to press before getting hacked to pieces! It allows for amazing combos as you gain new spells. Anyway, i rarely have the conviction to finish a game but this kept me amused. Its only flaw is its lack of 3D cutscenes....they're mostly 2D images with (i admit, decent) voice acting. Oh and there's great weapons and armour also and its customisable by special stones.
Great fun! If you like rpgs, or dungeon crawlers you'll especially love this. Great value for the price too :) I need to play the first one now!! :D
