For playing The Eye of Judgment: Legends on PSP you don't need a camera nor cards this time. But what remains then of the unique concept? Little to nothing. This time you get an in-game starter deck and collect more cards throughout the story or by buying them with money. The advantage of this is that you save a lot of cash (think of payable updates or the expensive investment in new cards) and you don't have to mess with a mat and the correct light strength for that upgraded eye toy.
