ドラゴンクエストモンスターズ
The game has Game Boy link cable support to facilitate two player battles against each other or together against the games AI, as well as allowing monster trading with players who had either version of the game. During player versus player combat, there is a possibility of stealing some of the other players monsters. To get all the keys available in the game, players must link up with another player playing the other version of the game. With the keys from the other title, all of the available worlds can be unlocked in the players own game. The PlayStation compilation featured improved graphics, new scenarios, and the ability to upload monsters players have caught to the i-Mode cellular version of the original "Dragon Quest Monsters".
