A role-playing game or RPG is a type of video game where the player controls one or several characters that are united in order to perform quests. Those quests are usually about fighting enemies (most of the time monsters in fantasy RPG) and combining the strength of every member of the party in order to defeat them. During the evolution of the game, the player and his different characters gain experience that makes them become stronger and allow them to fight stronger enemies.

Moreover, the characters have attributes like strength, stamina, intelligence, charisma and many others that evolve during the game and which make the character become what the player wants him or her to be. For instance if a player wants a character who is a master of magic he will improve the required characteristics.
