At many points in the game the player can choose between multiple lines of dialogue, with each answer advancing the plot in a different direction. Further choice presents itself as far as which direction to lead the battalion and which battle to take part in. The game mechanics of the Ogrebattle series are like none other. The main character, like all characters in the game, is defined via attributes such as strength, intelligence, agility, etc. Finally, every character is a member of a certain class.
Class is one of the most important concepts in the game.
As characters gain levels, they become eligible to change to a more powerful class. In the case of human characters, there is a choice of which class to take. At another point in the character's career, another class change may be possible with choices depending upon the first class choice. If a fighter had chosen to become a wizard, he probably wouldn't develop a high enough strength attribute to become a paladin later on. With some non-human classes, the change is not something to choose.
