"Dragon Quest" games have an overall upbeat feeling. The typical "Dragon Quest" plot involves the player controlling a party of heroes to defeat an ultimate evil villain, who usually threatens the world in some way. The plot-line often consists of smaller stories that involve encounters with other characters. This linear plot-line is intentional, to help ease the generally high learning curve RPGs have for those unaccustomed to them. The gameplay is designed to allow players to decide when, and whether, to pursue certain storyline paths. To ensure players continue to enjoy playing the game, no storyline path is made without some kind of reward and, to help ease players who may be apprehensive about whether they are on the right path, the distance the character has to travel to get rewarded is reduced at the beginning of the game. While the player never starts the game in a wholly non-linear way, they usually allow players to explore an open world in a non-linear manner following an early linear section of the game. Early character levels start players off with more hit points and a substantially increasing growth at later levels, although the effective bonuses of every additional level decreases.
