Batman Arkham Origins: Blackgate is a rather enjoyable game that I liked quite a bit on the Vita, though I don't know how the experience translates to a home console. My biggest deterrent with the game (which actually prevented me from finishing it) is the map. Forget the Joker, the map in Blackgate is Batman's most challenging foe. It's not so bad for traversing when doing missions (or even searching for collectables) but the endgame for Blackgate is very poorly constructed given the map is so bad.
That all being said, the map is supposedly fixed on the HD version so good luck to those that wish to pick it up. I think even for $5 you can enjoy it right up until the very end when you are sent on a ridiculous fetch quest.
