In most "Dragon Quest" games, players control a character or party of characters that can walk into towns and buy weapons, armor, and items to defeat monsters outside of the towns: on the world map or in a dungeon. However, in the original "Dragon Quest", there was only one character walking on the map. In most of the games, battles occur through random monster attacks and improving the characters' levels requires players to grind. The series uses cursed items, difficult dungeons where players need to use their resources wisely to complete them, and difficult boss battles. When the party encounters monsters the view switches perspective and players are presented with several options on a menu; these turn-based menu-driven battles have become a staple of the series. Players use the menus to select weapons, magic, and other items used to attack and defeat the monsters, or can attempt to flee the fight; though characters cannot flee during a boss battle. Once the party defeats the monsters by winning the battle, each party member gains experience points in order to reach new levels. When a character gains a new level, the statistics (stats) of the character are upgraded. Winning battles also rewards players with gold which can be used to purchase items. In addition to the experience points and gold awarded for successfully defeating monsters, occasionally, items will be dropped as well that are added to the player's inventory.
