Not owning a vita upon it's release here in the UK last Feb, I can imagine that a lot of people were put off by the hefty £35-£40 price tag this game came with. It's not a port of the iOS game completely, due to significantly improved graphics, better online functionality and some extra content, but it does still seem like one would be diddled after seeing this go for a few quid on the App Store.
However, for the significantly discounted price it's going at now, this Diablo-esque RPG is more than worth it. The game's generic, albeit slightly original storyline fills a hole, so to speak, but its real strengths come from the gameplay itself.
The controls are excellent, and make hacking and slashing through hordes of your typical fantasy fare an enjoyable experience. The story is relatively long, and has a lot of replay value once you take advantage of the seamless drop-in/drop-out online system. For commuters, or general hack n' slash fans, this is a well reasoned purchase, especially for just over a tenner. Besides, there's yet to be any real alternatives -YET- on the vita; so until then, go hunt some Dungeons!
