If there is any one game that will make me run out to grab a PS3 ... this is the game.
I've been a CCG junkie in the past ... and this combines two of my most cherished hobbies in life.
Gameplay Movie 4 gives a feel for how the cards will work. Also a nice long interview about the game as well. Sounds like it's going to be a full fledge CCG, with expansions, booster packs and so forth. Wizards of the Coast and Hasbro are involved in making the game and booster pack distribution.
For those saying it won't sell, from what I understand this type of gaming is extremely popular in Japanese Arcades right now ... I have a feeling the game will do extremely well in Japan and could possibly catch fire here in North America too.
Watch the Interview Vid ... it lay's it all out how the game works.
