I tried out a one shot at PAX Aus called GxB (GirlxBoy). The premise is thus: The GM is a new girl starting at a Japanese high school looking for love. The players are all other students at the school angling to win her heart. You’re playing out a Harem anime.
There’s not much to character creation beyond naming them and making a short bio (e.g. Sang Matsumoto: rich playboy, captain of the kendo club, has a chip on his shoulder about his half Korean heritage). You then each take turns asking the GM out, in character. You have to propose three date activities.
Each player then takes turn taking the GM on their proposed date. The thing is, the other players are in charge of describing what actually happens on your date and are trying to make you fail. For example:
Sang: I take her to a greenhouse full of flowers and start a monologue about how she is a thing of beauty.
Other players: The greenhouse is full of bees. Your date is getting stung by bees.
They GM has a deck of playing cards. If you do something she’s into, she gives you a card, facedown. If you upset her, she may take one of your cards back.
At the end of the game, the player reveals their cards and a scored by who got the most hearts. The player with the second most hearts has a chance to reveal a shocking secret about the person with the most hearts so that she chooses him instead. As an optional extra, the person with the most clubs dies tragically.
If you’ve got a group of people who are up on their anime tropes and know how to play them up, this game is hilarious.
