Ive never actually played a dating sim before, but Im confident in saying Hatoful Boyfriend is one of the weirdest ever released. Its a game where you play as the only human in a high school for birds, and your main goal is to woo your classmates: everyone from stuck-up doves to mysterious, aloof pigeons. There are ghost birds, biker bird gangs, crazy birds obsessed with pudding, and oh so many bird puns. Hatoful Boyfriend is probably the strangest thing Ive ever played, and its absolutely delightful.
