For an action game, Otogi has a decent amount of voice acting, most of which comes from the mysterious Princess who acts as your guide. For the most part, the English dub job is very well done and is every bit as good as the Japanese track. Though, Otogi does supposedly take place in a feudal Japan, so the option to revert to the original language track for a more 'authentic' feel is much appreciated.
Incompetent cameraman
If there's anything holding Otogi back from becoming an instant classic, it would be the camera system and indirectly, the control scheme. The camera is easily controllable with the right analog stick, except that during the times when you need a change in camera angle the most, your thumb is busy hitting buttons. Clicking the left thumbstick down immediately re-centers the camera, but it gets a little bothersome to have to constantly click the thumbstick just to see what you're up against. Hitting the left shoulder trigger will make the camera lock-on to a certain enemy, making sure that the camera never takes it lens off the target. That works fine for bosses or areas with few enemies, but it becomes less effective when you're surrounded.
