Abstract
A software product and a video game device for virtually performing a card game like a trading card game. Cards of the card game are given parameters each of which shows ability point or property of the card. When a player designates a first card to present it on a field (or “summon” the first card), an index parameter given to the card is compared with a threshold. If the index parameter is over the threshold, the player must “sacrifice” some cards from cards currently presented on the field in order to “summon” the first card.
Claims2
A software product to be executed by a video game device, representing a card game on a virtual field each of whose cards has at least one parameter, repeating processes comprising the process of:
- presenting a card from a player's hand on the field;
- computing a judgement with reference to parameters of the cards on the field;
- and
- removing at least one card according to the judgement;
- in order to represent one game,
- further comprising a card presentation process comprising the processes of:
- designating a first card from a player's hand;
- comparing an index parameter given to the first card with a predetermined threshold;
- designating at least one card from currently presented cards on the field as a sacrificed card if the index parameter is over the threshold;
- removing the sacrificed card from the field;
- presenting the first card;
- wherein the card presentation process decides the number of cards designated as sacrificed cards according to a parameter given to the first card.
A video game device performing a card game on a virtual field each of whose cards has at least one parameter, comprising processing units for:
- presenting a card from a player's hand on the field;
- computing a judgement with reference to parameters of the cards on the field;
- and
- removing at least one card according to the judgement;
- in order to representing one game,
- further comprising a card presentation processing unit comprising the processing units of:
- designating a first card from a player's hand;
- comparing an index parameter given to the first card with a predetermined threshold;
- designating at least one card from currently presented cards on the field as a sacrificed card if the index parameter is over the threshold;
- removing the sacrificed card from the field;
- and
- presenting the first card,
- wherein the card presentation processing unit decides number of cards designated as sacrificed cards according to a parameter given to the first card.
