Who’s Your Daddy, from the start, is a joke made in bad taste. It’s a multiplayer game where two players play a father and his infant son. The father's objective is to save the baby from all the dangers in the house, whether it’s by closing closets, hiding cleaning products, or deactivating the power outlets. On the other hand, the baby's gruesome mission is to end his own life as soon as possible.

Each round of the game lasts only a few minutes. The baby’s health deteriorates as he ingests harmful products or hurts himself with dangerous objects. If he dies, the game's over. The father’s objective is to keep him alive as long as possible until the mother arrives home and saves the family from catastrophe. Here, the game actually gets it right.
