Fantasy games are those that have themes and scenarios that exist in a fictional world. It is a genre that uses magic and other supernatural forms as a primary element of plot, theme, and/or setting. Fantasy is generally distinguished from science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there can be a great deal of overlap between the three.
Fantasy game elements usually include:
a- Creatures that are common in fantasy books and comics, such as orcs, trolls, goblins, dragons, etc.
b- Magic that can be used with units or abilities
c- Can involve a struggle between good and evil forces.
