Digimon Digital Card Battle (known as Digimon World: Digital Card Arena in Japan) is a PlayStation video game based on the Digimon franchise.The game is very different from the other Digimon releases since it is a totally card-based game. Players have a deck of 30 cards, [1] consisting of Digimon, support and special digivolution cards. The digivolution concept is similar to the other games, in that players start off with a Rookie and finish with an Ultimate (missing out Fresh, In-training and Mega, although Mega Digimon appear as Ultimate). Players sacrifice Digimon in their hand in order to build up "digivolution points" or DP. When one has enough for their desired Digimon, digivolution becomes possible. This brings a new tactical element to the game: deciding which cards to sacrifice.
