Player characters represent femininity. Monsters represent masculinity.
Players are free to explore the game world and hunt for gold in the swamps, woods, and fields, but are constantly pursued by monsters. This represents feminism and its repression.
Players can fight monsters as well, but are defenseless without weapons or spells, and can otherwise only attempt to flee. Trying to fight a monster with a sword but no shield usually results in the monster overtaking you, unable to repel him. Monsters sometimes emit heart symbols upon killing a player. This represents rape.
When successfully slain, most monsters drop gold. Succumbing to the same violent urges as the monsters rewards you with money. This is a metaphor for prostitution.
