Monster Rancher, known in Japan as Monster Farm (モンスターファーム?), is a console game released in North America on November 24, 1997, for the PlayStation system. It is the first game in Tecmo's Monster Rancher series, featuring the raising, fighting, and breeding of monsters.
Once the player has a monster, it can then be raised to be a fighting machine. There are six stats that determine how the monster does in battle: Power fuels physical attacks, Intelligence fuels and defends against energy attacks, Life determines monster's hit points, Skill affects accuracy, Speed helps evade opponents' attacks, and Defense reduces damage received from physical attacks. Monsters train either by doing chores nearby, or can be sent to be trained by experts, where they have the chance to gain new attack techniques.
Although it is possible to acquire a monster in-game, the series is known for the ability to acquire new monsters using Compact Discs (CDs). Players can use any readable CD, and the game creates a monster using the data stored on it. Certain CDs would result in unique monsters: for example, some Christmas music albums will give the player a monster of type "Santa". Once the player has two or more monsters in reserve, they can be combined, creating a new monster with traits of both 'parents.'
The primary way to advance through the game is through monster fighting tournaments. While in battle, each monster has attacks available to it, some moves are only available at close range, others from a distance. Players cannot control the monster directly in a fight, but can call for their monster to stay away or close in, and attack with whichever move is available at the current range.
