Fantasy games are defined by their setting rather than their mechanics — a tower defense game, an RPG, and an idle builder can all be fantasy games if they take place in a world with magic, mythical creatures, and invented lore. This means the category spans a huge range of difficulty levels and playstyles. A player who enjoys relaxing kingdom builders and a player who wants challenging combat RPGs will both find something in the fantasy tag. The common thread is imaginative world-building and a sense of entering somewhere that could not exist in real life.
