One of the novelties I didn't know about in the arcades, are these videogames in which you play with cards. The game recognize the cards and their positions over a table put in front of the player. The player also uses buttons and joysticks as usual.
I saw a medieval strategy game (the one in the photo), a football game, a Gundam RTS game and possibly others using this system. Quite an interesting idea to differentiate arcade games from anything on pc/home console.
