Demon Gaze Extra is a great version of one of the PS Vita's better DRPGs. It is worth getting for fans of the genre, but not essential for those who played the PS Vita original. The added features and content are nice to have, but the asking price is a bit too high right now to warrant a double dip.
Demon Gaze Extra takes a solid dungeon crawler, gives it a new coat of paint, and adds a little extra bits here and there to entice veterans to give it another go. I wouldn’t say that content is necessarily worth replaying the game for on its own, but those who haven’t played Demon Gaze yet will find a good, well-paced dungeon romp here. The story doesn’t really go anywhere that interesting, and those who don’t care for fan service will probably want to steer clear, but if what you crave is some dungeon RPG comfort food Demon Gaze Extra won’t let you down.
There’s a storyline, but since all of your characters are mute character portraits, all the dialogue and interactions come from the Inn’s colorful cast, most of whom I didn’t care for. I just don’t see the appeal of DGE. In the very crowded marketplace of JRPGs, there are way better choices out there.
