Luckily for us, Sony has much more forethought than I have, since The Eye of Judgment turns out to be one of the most innovative games in years. It's a darn good CCG as well. Utilizing the just-released PS Eye to turn your cards into actual 3D models on the screen, The Eye of Judgment offers the best example of augmented reality in videogames yet.
You place a card on the included cloth game mat and the camera identifies the card on the fly via a bar code type system, and a creature pops up on the screen. The game will keep track of all the gameplay elements for you, like how many cards you have in your library and your hand, what turn it is, and creature stats. The combination of holding real cards in your hands while also playing a video game is strangely thrilling, and not having to juggle all the rules and stats in your head is a nice change of pace from classic CCGs like Magic: The Gathering which have a rather ... complicated rule set.
