Frankly, I thought that even Gameloft's Uncharted clone, as crappy as it was, was a better game than Uncharted Vita. I've never felt as disrespected as a gamer by a developer as I did while playing Uncharted. Both Dead Space and Mass Effect (the iOS versions) are far better games than Uncharted -- they have better stories, better action, better combat mechanics, and far more challenge. The game pretty much encapsulates (and magnifies) everything that is wrong with contemporary console gaming. But it does look pretty, I'll give you that . And Sully is pretty cool.
Also agree with others about Shadow Guardian, it's not only the worst Uncharted style game I've played, but one of my biggest iOS purchase regrets.
