I was reminded this week of one of my more unusual favourites; The Eye Of Judgement for PS3.
It's a physical, card-based combat game that uses the PlayStation Eye camera for Augmented Reality with online play and vs CPU modes!
Here's a few more pics from it, you can see the box, the cards, a booster pack, the special stand for the PSEye camera, etc.
You can also poke the characters with your hands and they'll react!
Super oddball game and I love it.
