Both concepts lend themselves to enjoyable twitch game play that would seem to be the ideal matchup for a genre mixer. As I said, it sounds good on paper. Project Root is the latest downloadable title for our shiny new consoles and its mesh of the two genres is commendable. However, the parts that weigh it down are its punishing difficulty and obtuse direction.
