"Monster Hunter is an action game for the PlayStation 2. The game was developed and published by Capcom. Monster Hunter was released in North America on September 21, 2004. It was later remade and expanded in Monster Hunter G, which was released in Japan and was brought to North America and Europe as Monster Hunter Freedom for the PlayStation Portable.
Although much of the game can be played offline through single-player, the majority of the content is in the online section of the game. Not all of the monsters are found in single-player and the player's rewards are smaller when they are offline. The goal for players online is not to defeat the most monsters but to reach the highest hunter rank, which is the storyline that is carried out online by NPC characters."
